fix(autodj): exclude trim-silence bins from edge span and fade length

Edge analysis rounded contentStart/End back to bins, which could land inside trim-silence. With the 5 s trim cap, playback seeks partway through a long digital tail but bins between the seek point and real music were still counted in edge.seconds — empty tail/head time leaked into fade duration. Anchor walks at the first/last audible bin (peak > cut) inside the playback window, skip trim-silence in run/shape collection, and measure plateau only over playable content. Adds contentPlayBinRange() shared with computeWaveformSilence.
fix(autodj): equal-power edge-mix curve + STANDARD_BLEND floor for hard loud↔loud

-// Architecture / layering guard for the feature-folder structure (PR #1225, group A1).
-//
-// Encodes the layering contract the restructure established:
-//
-//   lib                     (feature-free infra: api clients, format, i18n, util, media, server, navigation)
-//     ▲
-//   store / ui              (cross-cutting global stores; domain-agnostic primitives) — may import lib
-//     ▲
-//   cover / music-network   (top-level domains — peers; may import lib, store, ui)
-//     ▲
-//   features/<x>            (may import lib, store, ui, cover, music-network, other features via barrel only)
-//     ▲
-//   app                     (shell + bridges — may import anything)
-//
-// A lower layer may NOT import a higher one. Cross-feature access goes through the
-// `@/features/<x>` barrel only, never a deep path. No import cycles anywhere.
-//
-// Ratchet: current known violations (residual legacy dirs + documented inversions) are
-// captured in `.dependency-cruiser-known-violations.json` and ignored via `--ignore-known`
-// (see `npm run dep:check`). Any NEW violation fails CI. As the drain (group E) removes an
-// exception, regenerate the baseline so the count ratchets toward zero.

-## Added
-
-### Square corners — sharp-edged cards and covers
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1215](https://github.com/Psychotoxical/psysonic/pull/1215)**
-
-* New **Square Corners** toggle under **Settings → Appearance → Visual Options → Display** overrides the active theme to render cards and cover art with square, non-rounded corners. Covers album, playlist, artist and song cards, detail-page cover art, the Now Playing / Radio and fullscreen views, the cover lightbox, the queue cover, and the mini player. Off by default; buttons, inputs and dialogs keep the theme's corners.
-
-### Discord community banner
-
-**By [@ImAsra](https://github.com/ImAsra), PR [#1222](https://github.com/Psychotoxical/psysonic/pull/1222)**
-
-* A dismissible banner inviting you to join the Psysonic community on Discord appears after 20 hours of accumulated app use. **Join** opens the invite; dismiss it for the session, or choose **Never show again** to hide it permanently. The icon renders at a consistent size on every platform, including Windows.
-
-### Bulgarian translation
-
-**By [@akirichev](https://github.com/akirichev), PR [#1228](https://github.com/Psychotoxical/psysonic/pull/1228)**
-
-* Full Bulgarian (Български) UI translation — selectable from the language picker on the Settings and Login screens.
-
-### Artists browse — album vs track credit mode
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1232](https://github.com/Psychotoxical/psysonic/pull/1232)**
-
-* Toggle **Album artists** vs **Track artists** on the Artists page — album mode lists indexed album artists; track mode includes performers from the local artist index (featured/guest credits). Star filter works in both modes; the choice persists across app restarts like **Show artist images**.
-* Letter bucket filter (`A`–`Z`, `#`, `OTHER`) runs in local SQL instead of scanning catalog chunks client-side, so late-alphabet picks load promptly on large libraries.
-* Artist name search no longer depends on query letter case for Cyrillic (and other non-ASCII) names when the local library index is enabled.
-
-### CLI — relative volume and quieter scripting output
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1238](https://github.com/Psychotoxical/psysonic/pull/1238)**
-
-* `psysonic --player volume +5` / `volume -10` adjust the current level by that many percent; `volume 80` still sets an absolute level (use `-q` before `--player` when the delta is negative so it is not parsed as a flag).
-* CLI invocations no longer print WebKit/NVIDIA workaround notes on stderr; on Linux, remote `--player` forwarding runs before WebKit startup so helper processes exit with less noise.
-
-### Theme Store — per-theme changelogs and pinned updates
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1240](https://github.com/Psychotoxical/psysonic/pull/1240)**
-
-* Each theme card now has an expandable **What's new** with per-version release notes, so you can see what a theme update changed — including non-visual fixes. Provided by theme authors; themes without notes just don't show the section.
-* Installed themes with an available update now appear at the top of the store list instead of wherever the sort placed them, so you don't have to hunt for them.
-
-### Multi-library filter — browse and search across selected libraries
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1241](https://github.com/Psychotoxical/psysonic/pull/1241)**
-
-* The sidebar library picker now supports **multi-select with priority ordering**: browse, search, genre and album/artist detail views aggregate across the chosen libraries and de-duplicate shared items by priority. Built for large libraries — scoped SQL uses the hot `library_id` column with covering indexes and FTS-first matching.
-* Identity matching that powers cross-library de-duplication now normalises names per shipped locale (folds German ß, Norwegian æ, French œ, Romanian ș/ț, and Cyrillic ё/й); CJK titles are matched as-is.
-* The Genres page and album browse genre filter list the full catalog on large libraries when **All libraries** is selected.
-
-### Theme contributors credited in Settings
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1248](https://github.com/Psychotoxical/psysonic/pull/1248)**
-
-* **Settings → System → Contributors** now lists community theme authors in a **Themes** sub-section alongside the **App** contributors, pulled from the theme store so it stays current as new themes are published.
-* The theme card **What's new** now shows just the latest version's notes instead of the full version history.
-* Theme author names refresh quietly from the store in the background instead of staying stale for up to 12 hours.
-
-### Fullscreen player — Minimal and Immersive styles
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1249](https://github.com/Psychotoxical/psysonic/pull/1249)**
-
-* **Settings → Appearance → Fullscreen player style** lets you choose **Minimal** (the current view) or **Immersive** — the earlier fullscreen player, with the artist photo/backdrop, a cover-derived accent colour, and rail or Apple-style scrolling lyrics.
-* In Immersive, **Show artist photo** and **Photo dimming** are configurable; Apple-style lyrics show the artist image as a dimmed full-screen backdrop.
-
-### Italian translation
-
-**By [@daquino94](https://github.com/daquino94), PR [#1250](https://github.com/Psychotoxical/psysonic/pull/1250)**
-
-* Full Italian (Italiano) UI translation — selectable from the language picker on the Settings and Login screens.
-
-### Fullscreen player — Prism style
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1251](https://github.com/Psychotoxical/psysonic/pull/1251)**
-
-* A third **Fullscreen player style**, **Prism** — a full-bleed artist backdrop with a floating glass lyrics panel on the right and a single glass control bar at the bottom (transport, a centred now-playing pill with an integrated progress line, and utilities). The cover-derived accent colour drives the progress fill and the active lyric line, and upcoming lyric lines fade out with a progressive blur.
-
-### Lyrics — word-by-word highlighting straight from your server
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1265](https://github.com/Psychotoxical/psysonic/pull/1265)**
-
-* The **Server** lyrics source now highlights lyrics word by word, so karaoke sync no longer depends on the third-party YouLyPlus backend. Requires Navidrome 0.63 or newer and lyrics that carry word timing (TTML or Enhanced LRC); anything else keeps highlighting line by line.
-* **Settings → Lyrics → Lyrics Sources** spells out those requirements, and the block now follows the standard settings sub-card layout.
-* Embedded Enhanced LRC no longer prints raw word timing codes (`<00:12.34>`) in the lyric text — those codes drive word-by-word highlighting instead.
-* FLAC, Ogg Vorbis, Opus and Speex files that store synced lyrics in the `SYNCEDLYRICS` tag show embedded lyrics again, with that tag taking priority over the plain `LYRICS` tag.
-
-### Start minimized to tray
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1271](https://github.com/Psychotoxical/psysonic/pull/1271)**
-
-* New **Start Minimized to Tray** toggle under **Settings → System → Behavior**. When enabled, the next cold start keeps the main window hidden and Psysonic runs from the system tray until you show it from the tray icon.
-* Requires **Show Tray Icon** (turning this on enables the tray automatically; hiding the tray clears the setting). The choice applies on the next launch only — toggling it in Settings does not hide the window immediately.
-* Opening the main window from the tray after a cold start renders the sidebar and main content immediately — including on Linux tiling WMs such as Hyprland — instead of leaving the sidebar or Mainstage invisible or blank until a restart.
-
-### Navidrome public share links — open and play without logging in
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1275](https://github.com/Psychotoxical/psysonic/pull/1275)**
-
-* Paste or search a Navidrome **public share** URL (`/share/{id}`) to preview the shared track list in a modal, then play the full queue with no server account — direct stream and cover URLs are resolved anonymously from the share page.
-* Share playback uses a dedicated scope so an idle server play-queue pull cannot replace the share queue while you are also logged into Navidrome. Share sessions are not restored after an app restart — the server play queue applies as usual.
-* While a share queue is active, **Save Playlist** is hidden in the queue toolbar (share tracks cannot be saved to the server); **Load Playlist** stays available. The queue **Share** button copies the original Navidrome `/share/{id}` page URL.
-
-### Track lists — optional album cover thumbnails
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1280](https://github.com/Psychotoxical/psysonic/pull/1280)**
-
-* Browse and queue track rows can show the track's **album** cover (per-disc art when the album has distinct disc covers). Covers load through the standard cover cache pipeline — library resolve, viewport ensure, Rust resize to disk tiers — not a separate warm path.
-* **Settings → Appearance** adds separate toggles for queue vs browse tracklists. Favorites, playlist, and album-detail track grids gain a flex-resize handle on the title column when covers are shown.
-* Album detail pages skip per-row cover thumbs when the album art is already shown above the list — no duplicate image on every line.
-
-### Discord — server cover art source, without the credential leak
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1299](https://github.com/Psychotoxical/psysonic/pull/1299)**
-
-* **Settings → Integrations → Discord → Cover art source** gets a **Server** option, alongside **None** and **Apple Music**. It resolves artwork through the standard Subsonic `getAlbumInfo2` endpoint's public image link — never an authenticated cover URL that could expose your login credentials (reported by lavioso on Discord). Needs a publicly reachable server; anyone viewing your Discord profile can see that server's public address, but nothing else.
-
-### Playlist cards — play and queue from the right-click menu
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1307](https://github.com/Psychotoxical/psysonic/pull/1307)**
-
-* Right-clicking a playlist card now offers **Play next** and **Add to queue** alongside **Play now**, matching the album card. All three honour offline mode and the active multi-library filter.
-
-### Playlists browse — scoped header search
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1308](https://github.com/Psychotoxical/psysonic/pull/1308)**
-
-* The header search field on the Playlists page now filters the list by playlist name (same scoped badge pattern as Artists / Albums), including in folder view.
-
-### Artist page — add the whole discography to the queue
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1321](https://github.com/Psychotoxical/psysonic/pull/1321)**
-
-* A new queue button on the artist page appends the artist's entire discography to the current queue in one click, next to Play all and Shuffle — matching what album pages already offer.
-
-
-## Changed
-
-### Frontend restructure — feature-folder architecture and hardening
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), with additional architecture by [@cucadmuh](https://github.com/cucadmuh), PR [#1225](https://github.com/Psychotoxical/psysonic/pull/1225)**
-
-* Reorganised the frontend into a feature-folder architecture with a CI-enforced layering guard, added unit + behavior-scenario + boot-smoke test coverage, and introduced a compile-time frontend/backend IPC contract via tauri-specta. Internal only — no change to how the app looks or behaves.
-
-### Typed-IPC contract — completed the tauri-specta cutover
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), with additional architecture by [@cucadmuh](https://github.com/cucadmuh), PR [#1230](https://github.com/Psychotoxical/psysonic/pull/1230)**
-
-* Completed the frontend/backend typed-IPC contract: the frontend now calls the generated tauri-specta command surface, with CI guards keeping the bindings fresh and every command registered in the handler. Internal only — no change to how the app looks or behaves.
-
-### Equalizer — per-device profiles follow the active system default
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1274](https://github.com/Psychotoxical/psysonic/pull/1274)**, suggested by [@JustBuddy](https://github.com/JustBuddy)
-
-* With **Remember EQ per device** enabled and **System Default** selected, the equalizer now keys profiles to the active OS default output and switches when that default changes externally (Windows sound settings, Stream Deck, etc.), instead of using one shared profile for all system-default outputs.
-* On Linux/PipeWire, the active default is resolved from WirePlumber (`wpctl`) first — including Hyprpanel, pavucontrol, and `wpctl set-default` — not cpal, which can keep a stale card name even after the default sink changes. When PipeWire has already moved the playback stream to the new default, the device watcher skips a redundant stream reopen (avoids a post-switch stutter).
-* **Windows:** release builds no longer freeze on the loading splash; audio output devices on Windows and macOS use stable backend IDs with clearer labels, duplicate friendly names are disambiguated, device-change detection works again, and legacy pinned device / per-device EQ keys stored as plain names are matched after upgrade.
-
-### Player bar — build your own
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1287](https://github.com/Psychotoxical/psysonic/pull/1287)**
-
-* **Settings → Personalisation → Player bar** now also hides the **stop button** and shows the **album name** under the artist (off by default; clicking it opens the album). The right-hand buttons — star rating, favorite, love, playback speed, equalizer, mini player — can be **dragged into any order** you like.
-* The section is no longer behind **Advanced**.
-
-### Shuffle
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1288](https://github.com/Psychotoxical/psysonic/pull/1288)**
-
-* A **shuffle toggle** in the player bar, next to the transport controls. While on, the queue is shuffled from the current track onwards — the playing track stays put — and turning it off restores the original order. It survives a restart, and the shuffled order is what your other devices and Orbit guests see, so playback stays in step everywhere. Hide the button under **Settings → Personalisation → Player bar** if you don't want it.
-
-## Fixed
-
-### Per-track covers when playing from a playlist
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1218](https://github.com/Psychotoxical/psysonic/pull/1218)**, reported by The Cup Slammer on Discord
-
-* Playing a song from a playlist could show the song's own cover art in Now Playing instead of its album cover, while playing the same song from its album page showed the album cover. Now Playing now consistently uses the album cover, matching album-page playback. Albums with genuine per-disc artwork are unaffected.
-
-### Playback — ReplayGain prefetch, gapless playbar sync, and library peak index
-
-**By [@cucadmuh](https://github.com/cucadmuh), reported by Asra on the Psysonic Discord, PR [#1231](https://github.com/Psychotoxical/psysonic/pull/1231)**
-
-* ReplayGain applies when stream or queue metadata resolves late — index-first prefetch before bind, reactive sync when resolver tags land, and live refresh from the library index after sync when tags differ on the playing track.
-* Gapless auto-advance no longer leaves the playbar on the previous track; missed `audio:track_switched` is reconciled from engine position with seek guards so backward seek is not treated as a gapless switch.
-* Local library index stores `replayGainPeak` (migration 015) so anti-clipping peak is available on index-first paths without an extra network round-trip.
-
-### Connection — ignore spurious offline hint on desktop
-
-**By [@cucadmuh](https://github.com/cucadmuh), reported by mikmik on the Psysonic Discord, PR [#1234](https://github.com/Psychotoxical/psysonic/pull/1234)**
-
-* Desktop builds no longer get stuck showing "offline" when WebKitGTK leaves `navigator.onLine` stuck at `false` while the server is actually reachable — the app now confirms with a real server probe instead of trusting that hint, so browse and playback keep working. Web builds are unchanged.
-* Pending favorite/rating sync now flushes when the server actually becomes reachable again, rather than relying on a browser `online` event that may never fire on desktop.
-
-### Playlists — add more than ~341 tracks; faster large-playlist edits
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1235](https://github.com/Psychotoxical/psysonic/pull/1235)**
-
-* Adding tracks to a playlist no longer fails past ~341 songs — writes are sent to the server in batches instead of one oversized request, so playlists of any size build correctly.
-* Adding and merging into large playlists is faster: playlist membership is cached in memory for de-duplication instead of re-fetching the whole playlist on every add.
-
-### Queue — rows no longer stuck showing "…"
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1236](https://github.com/Psychotoxical/psysonic/pull/1236)**
-
-* Queue rows that were far from the currently playing track (e.g. after starting a large playlist from the middle, or scrolling the queue) no longer stay stuck on a "…" placeholder — the queue now loads track details for whatever you scroll to, in the desktop queue panel, the mobile queue drawer, and the fullscreen "up next" overlay.
-
-### Offline browse — on-disk-only Artists, Albums, Tracks, and Genres
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1243](https://github.com/Psychotoxical/psysonic/pull/1243)**
-
-* When browsing offline, Artists, Albums, Tracks, and Genres now list only content with on-disk bytes — library pins, favorites-auto saves, and hot-cache playback — instead of the full server or local index catalog.
-* Sidebar and shell gates react when hot-cache rows appear; browse pages reload after hot-cache growth and library sync without leaving the page.
-* Album vs track artist credit mode, starred artists, genre filters, and Tracks discovery rails respect the on-disk scope; album artist grouping follows indexed `album_artist` parity.
-
-### All Albums — year filter keyboard entry
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1244](https://github.com/Psychotoxical/psysonic/pull/1244)**
-
-* The year filter on All Albums no longer clamps on every keystroke while typing a four-digit year — drafts commit on blur, Enter, or outside click; incomplete input reverts to the last applied value. Wheel and spinner controls are unchanged.
-
-### Album detail — favorite heart and album-level stars
-
-**By [@cucadmuh](https://github.com/cucadmuh), reported by HiveMind on the Psysonic Discord, PR [#1247](https://github.com/Psychotoxical/psysonic/pull/1247)**
-
-* Starring an album on the detail page now fills the heart immediately and keeps it filled after reload or returning from Favorites — the local index stores album favorites in `album.starred_at` instead of inferring from track stars.
-* When only a track is starred, the album heart stays empty unless the album itself is in Favorites; unfavorite no longer requires a double click on the detail page.
-* Album user rating on detail reconciles from the server in the background; multi-library browse and Favorites filters use album-level stars consistently.
-
-### Library — renamed artists no longer linger as ghosts after resync
-
-**By [@cucadmuh](https://github.com/cucadmuh), reported by Seraphim on the Psysonic Discord, PR [#1253](https://github.com/Psychotoxical/psysonic/pull/1253)**
-
-* Renaming an artist on the server no longer leaves a stale entry in the local Artists list that opened to "Artist not found" — a sync now prunes artist rows the latest server listing no longer confirms that also have no remaining tracks. Cleanup runs on both full and delta syncs (only after a confirmed artist listing, so a transient empty response can't drop valid entries), plus a one-time pass at startup that clears ghosts already accumulated in existing libraries.
-* Newly added or renamed entries now show up right after a resync instead of only after an app restart: the Artists and Albums pages refresh their cached catalog when a library sync finishes.
-
-### Library — album artist links no longer dead-end at "Artist not found"
-
-**By [@cucadmuh](https://github.com/cucadmuh), reported by tummydummy, PR [#1254](https://github.com/Psychotoxical/psysonic/pull/1254)**
-
-* Clicking the artist beneath an album (most visibly in **Random Albums**) no longer shows "Artist not found" when the server's `getArtist` doesn't recognise that album-artist id — the artist page now falls back to the local library index, which shares the id the card was built from. Artist pages also stay reachable on a brief network hiccup when the library is indexed.
-
-### Library — album tiles no longer miss cover art in Random Albums
-
-**By [@cucadmuh](https://github.com/cucadmuh), reported by tummydummy, PR [#1254](https://github.com/Psychotoxical/psysonic/pull/1254)**
-
-* Album tiles for rows that synced without a cover id (surfacing most in **Random Albums**) no longer show a blank cover while the detail page has one — local browse now falls back to the album's first track cover id, so tile and detail resolve the same artwork. The same fallback applies to the detail header's library cover resolution, so the two stay consistent instead of flickering between art and placeholder.
-
-### Library — multi-library dedup sidecar no longer accumulates dead identity keys
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1255](https://github.com/Psychotoxical/psysonic/pull/1255)**
-
-* The precomputed `library-cluster.db` identity keys used for cross-library dedup are now pruned on rebuild when their track no longer exists (removed, or dropped when a server mints a fresh id on rename). Previously the rebuild only refreshed live tracks and never deleted stale rows, so the sidecar grew with library churn until it was recreated wholesale (server switch / restore / import). The rows were inert (reads only ever join live tracks), so dedup and browse results are unchanged — this just stops the sidecar from bloating.
-
-### Library — renamed album artist links now heal on resync
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1256](https://github.com/Psychotoxical/psysonic/pull/1256)**
-
-* When an artist is renamed on the server (minting a new artist id), the album's stored artist link no longer stays stuck on the old id and dead-ending at "Artist not found". Album metadata now follows the server's `getAlbum` for the artist reference, so a resync updates it instead of keeping the pre-rename id indefinitely. Complements the earlier ghost-row prune (#1253) and the local-index fallback (#1254), which did not clear the stale reference itself.
-
-### Sync — large play queues no longer revert after pausing
-
-**By [@norperz](https://github.com/norperz), PR [#1262](https://github.com/Psychotoxical/psysonic/pull/1262)**
-
-* Pausing a large queue behind a reverse proxy (e.g. Nginx) could snap the player back to an earlier track — the save was one long URL that hit the HTTP 414 limit, failed silently, and idle auto-pull restored the stale server queue.
-* Servers advertising the OpenSubsonic `formPost` extension (Navidrome) now save via POST; others retry once as POST on 414. A failed save no longer lets auto-pull overwrite playback — it resumes only after a successful save.
-
-### Servers — connecting to servers behind a header gate

-
-* Adding a server that needs a custom HTTP header (Cloudflare Access, Pangolin service tokens) failed with "Connection failed" even though streaming and covers would have worked. Root cause: the connection test ran in the WebView, which sends a header-less CORS preflight the gate rejects before the real request. The test now runs natively for header-carrying servers, so the header rides on the request and the server connects.
-* A failed "Add server" used to close the form and leave only a tiny status dot, so it was unclear what went wrong. The form now stays open on failure and shows the reason — the server's own message (e.g. "Wrong username or password"), an HTTP status like `HTTP 403 Forbidden`, or a transport error — and empty server address / username are caught up front with a clear message.
-* Even after a gated server connected, browse and detail views that run in the WebView — Main stage, New Releases, Random Albums, Statistics, search, genres, and more — stayed empty, because those `axios` requests still tripped the gate's CORS preflight. Every Subsonic REST call that would carry a gate header now runs natively (the same reqwest path streaming and covers use), so the whole app works behind a header gate, not just playback.
-* Playback itself and background prefetch still returned `403` on a gated server: the audio/preload path attached the gate header only when its playback server id happened to match the header registry key, and silently sent nothing otherwise. Header lookup now falls back to matching the request URL against the server's own endpoints (the same fallback covers and Navidrome browse already used), so streaming, prefetch and artist-info fetches carry the header reliably. Endpoint matching only ever hits a configured gated server and still honours the *apply to LAN/public* rule, so non-gated servers are untouched.
-* Under the extra native-proxy traffic a gated server now generates, browse calls opened a brand-new connection pool per request, which starved connections and made fast endpoints time out. Proxied requests now reuse a pooled HTTP client, keeping keep-alive across the burst of browse calls.
-* On app startup the per-server gate headers were registered with the native layer only after a successful reachability probe and bind — so if that probe was slow or the server looked briefly offline, the registry stayed empty and every native request (streaming, covers, prefetch, artist art) 403'd behind the gate even though the header was configured. Headers are now registered up front, before any probe or bind, so the native layer always has them.
-* Covers that hit the gate during the brief window before headers were registered got a `403`, which was treated as "cover missing" and written a 30-minute do-not-retry marker — so on a gated server most covers stayed blank long after the gate started answering. A gate-style `403`/`401` on cover art is now treated as a recoverable hiccup (retried) rather than a permanent miss, and reconnecting a gated server clears those stale markers and re-runs the cover fill so the artwork loads.
-* For a server with both a LAN and a public address, whichever answered first after launch stuck for the whole session: if the app started off the LAN it pinned to the public address and never switched back to LAN once you got home (the public address kept answering, so the LAN address was never re-checked). The reachability tick now re-checks the LAN address first with a single attempt, so returning to the LAN upgrades the connection back to local automatically, while staying remote costs just that one probe rather than the full retry wait. The LAN/public badge also refreshes immediately when you switch the active server, instead of staying on the previous server's classification until the next poll.

-### Windows — MSI bundle on dev and RC versions
-

-
-* Windows `.msi` builds no longer fail on channel versions like `1.50.0-dev` — WiX requires a numeric fourth version field, so the bundler maps `-dev` / `-rc.N` to numeric semver in `bundle.windows.wix.version` while Settings → About still shows the real package version.

-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1284](https://github.com/Psychotoxical/psysonic/pull/1284)**
-
-* Internet Radio playback stayed on HTML5 after v1.32, but EQ changes only reached the Rust engine used for library tracks — toggling EQ or switching presets had no effect on a live station. Radio now routes through a Web Audio 10-band graph on the same `<audio>` element when EQ is enabled; preset and slider changes update filters in place without restarting the stream.

-
-* Connecting a scrobble service could fail with only "Network error — check your connection or URL", which covers everything from a DNS failure to a blocked host, an interrupted TLS handshake or a rejected request. The underlying error is now shown alongside it, so a failing connect can be told apart from a reachability problem on your machine or network.

-
-* Windows release builds could send `psysonic/undefined` as the Subsonic client id (visible in **Who is listening?**) when `package.json` version was read during a circular authStore boot-chunk init — prebuild now emits a leaf `SUBSONIC_CLIENT_ID` literal and the boot-chunk guard rejects unresolved client-id templates.

-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1292](https://github.com/Psychotoxical/psysonic/pull/1292)**
-
-* Sorting albums by artist ordered them by the track artist while showing the album artist. On a release with featured guests the two differ, so it was filed under a name that isn't on screen — the album dropped out of its artist's run of years, sometimes behind a different artist entirely. Album sorting now follows the artist the row actually shows.

-**By [@cucadmuh](https://github.com/cucadmuh), reported by VirtualWolf, PR [#1295](https://github.com/Psychotoxical/psysonic/pull/1295)**
-
-* Custom playlist and internet radio covers uploaded in Navidrome stayed blank in Psysonic (cards and detail headers) while album and track art worked. The cover resolver rewrote Navidrome's `pl-*` and `ra-*` getCoverArt ids into invalid `al-pl-*_0` / `al-ra-*_0` forms; fetch-only prefixes are now preserved in TS and Rust.

-### Themes — album rails no longer cut off card shadows
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), reported by Asra on the Psysonic Discord, PR [#1300](https://github.com/Psychotoxical/psysonic/pull/1300)**
-
-* Horizontal album rails clipped an outer card shadow at the edges, which only themes that use a real drop shadow ran into. Working around it meant overriding the rail's `overflow`, and that disabled the rail's `<` / `>` scroll arrows. Rails now reserve room for the shadow inside the rail itself, so the arrows keep working; a theme that needs more room can raise `--rail-shadow-room` instead of touching `overflow`.

-**By [@AliMahmoudDev](https://github.com/AliMahmoudDev), PR [#1301](https://github.com/Psychotoxical/psysonic/pull/1301)**
-
-* Modal dialogs carried no accessible name, so a screen reader announced them without saying which dialog had opened. The dialog is now linked to its title, and each instance gets its own id so several open dialogs cannot be confused for one another.

-
-* With a large number of community themes installed, every hover or playback-state change made the browser re-evaluate the CSS of every installed theme, which could slow the UI to a crawl. Only the active theme (plus the scheduler's day and night picks) participates now; the others stay dormant until applied — switching themes is unaffected.

-* **Settings → Audio → Native Hi-Res** gains a blend-rate picker (44.1 / 88.2 / 96 kHz, default 44.1 kHz) for transitions when adjacent tracks have different sample rates, with a note that resampling uses extra CPU and memory.
-* **Crossfade / AutoDJ:** both sides resample to the chosen rate; the output stream reopens when needed and the outgoing track rebuilds from cache so mixed 88.2 ↔ 44.1 kHz transitions no longer tear mid-fade.

+* AutoDJ now blends tracks using the **shape of the audio at each edge** — it measures how each track ends and how the next one begins, then crossfades over exactly that musical region with matched gain curves instead of a generic equal-power fade. Transitions follow real fade-outs and intros more closely; smooth skip uses the same model from your current position.
+* Blend curves use **equal-power interpolation** between waveform-derived gain endpoints (constant perceived loudness during the overlap, like classic crossfade), and **hard loud↔loud** pairs get at least a ~2 s overlap so stabs and abrupt endings still feel blended.
+* New **Transition length** controls under Settings → Audio → Track transitions: optional **Min** and **Max** bounds (each with an **Auto** setting) cap how short or long an AutoDJ blend can be. Auto leaves the length entirely up to the audio.

-### Genres page kept empty genres after tag changes
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1176](https://github.com/Psychotoxical/psysonic/pull/1176)**, closes [#1162](https://github.com/Psychotoxical/psysonic/issues/1162)
-
-* After retagging a track and resyncing the library, genres with no remaining albums could still appear on the Genres page until restart. The local genre catalog now counts only live indexed tracks, filters zero-count genres, and the Genres page refreshes when library sync finishes.
-
-### AutoDJ — last track in the queue was cut short
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1183](https://github.com/Psychotoxical/psysonic/pull/1183)**
-
-* With AutoDJ active and no next track to blend into, the engine could still fire the crossfade end timer and trim the final song. The last track now plays through to real source exhaustion.

-### Play queue sync — idle pull rewound after the queue finished
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1183](https://github.com/Psychotoxical/psysonic/pull/1183)**
-
-* After the last track ended (repeat off), idle auto-pull could restore an earlier server position from the last debounced push and seek backward. The client now flushes end-of-track position to the server and skips idle auto-pull until playback resumes, the queue is edited, or the user pulls manually.

-
-* Strengthens the existing disconnect/recovery path: connection status is now shared across all `useConnectionStatus` hook instances, so a successful **Retry** on the offline banner clears offline-browse sidebar filtering in step with the header connection indicator (no app restart).

-### Timeline play history disappeared on album/playlist play
-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1204](https://github.com/Psychotoxical/psysonic/pull/1204)**, closes [#1096](https://github.com/Psychotoxical/psysonic/issues/1096)
-
-* Timeline mode now keeps a session play-history strip (plus cold bootstrap of the last 50 plays from statistics) when Play album/playlist replaces the queue; canonical queue sync is unchanged.
-* The current track stays pinned to the top of the list; clicking a history row inserts after the playing track instead of replacing the queue, and replayed tracks remain in the history strip.
-* History rows from other servers resolve album/cover metadata per server so Now Playing artwork loads when replaying cross-server plays.
-* Cross-server queue switches now send `playbackReport` **stopped** to the previous server so its Who is listening entry clears promptly.
-
-### Album and artist covers — full resolution restored
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1205](https://github.com/Psychotoxical/psysonic/pull/1205)**
-
-* Album and artist covers — and the full-size view when you click a cover — could appear small and low-quality even though the source image was large, depending on how you reached the album. Root cause: the cache built its larger sizes from a smaller already-saved size instead of the full-resolution download, so they were stored downscaled. Covers are now built from the full-resolution image, and the full-size view opens at full resolution. The cover cache refreshes once on update. Reported by users on Discord.

-
-**By [@cucadmuh](https://github.com/cucadmuh), PR [#1170](https://github.com/Psychotoxical/psysonic/pull/1170)**
-
-* Strict `npm run lint` runs in CI on frontend path filters via a dedicated workflow parallel to the existing frontend test jobs.
-* The `ci-ok` check waits for every applicable test and lint job on a PR (frontend and/or Rust, depending on changed paths) and blocks merge when any required job failed or did not finish in time.
-
-### Settings — consistent design for the Audio sub-sections
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1175](https://github.com/Psychotoxical/psysonic/pull/1175)**
-
-* The AutoDJ overlap-cap and the Native Hi-Res blend-rate options in Settings → Audio now sit in the same bordered sub-card the Normalization options use, and the Hi-Res section no longer shows a double border.
-
-### App no longer blanks on an unexpected error
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1194](https://github.com/Psychotoxical/psysonic/pull/1194)**
-
-* If a screen hit an unexpected rendering error, the whole window could go blank with no way back. The app now shows a small recoverable error card (Try again / Reload app) instead, and playback keeps going.
-
-### Windows update notice waits out WinGet moderation
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1200](https://github.com/Psychotoxical/psysonic/pull/1200)**
-
-* On Windows, the "update available" notice now waits until a release is a couple of days old, so it no longer points to a version that WinGet has not finished publishing yet. macOS and Linux are unaffected.
-
-### Playlist no longer reloads when you press Play
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1201](https://github.com/Psychotoxical/psysonic/pull/1201)**
-
-* Pressing Play, Shuffle or Add to queue on a playlist no longer reloads the whole page with a spinner — it just starts playback. Editing the playlist (adding or removing songs) still refreshes the list as before.
-
-### Sidebar items jumped back when reordered
-
-**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1206](https://github.com/Psychotoxical/psysonic/pull/1206)**, reported by [@tummydummy](https://github.com/tummydummy)
-
-* In Settings → Personalization → Sidebar, dragging an item to a new position could snap it back or land it one place off, depending on which items were hidden. Reordering now tracks each item directly, so it stays exactly where you release it — both in the customizer and when long-pressing items in the sidebar itself.

Other locales may be left for follow-up translation PRs if you don't speak the language, but keep the object shape consistent so missing keys are obvious.

When a locale introduces a script or letters it does not yet cover, extend its decomposition table for that language and **bump `NORM_VERSION`** (existing `library-cluster.db` keys rebuild automatically). CJK locales are intentionally left verbatim. The module header carries the same checklist.

-## Frontend architecture and layering
-
-The frontend uses a feature-folder architecture (introduced in #1225) with a layering contract that CI enforces through **`npm run dep:check`** (dependency-cruiser). The rule is simple: **a lower layer must never import a higher one.**
-
-```
-lib  →  store / ui  →  cover / music-network  →  features/<x>  →  app
-```
-
- **`lib/**` is the floor** — feature-free infrastructure (API clients, formatting, i18n, util, media, server, navigation). It must **not** import from `store`, `ui`, `features`, `cover`, `music-network`, or `app`. If a `lib` helper needs auth/server state, pass it in as an argument or keep the helper in the layer that owns that state (`store` or `features`) — do not reach into a store from `lib`.
- **`store` / `ui`** may import `lib` only.
- **`cover` / `music-network`** are top-level domains and may import `lib`, `store`, `ui`.
- **`features/<x>`** may import `lib`, `store`, `ui`, `cover`, `music-network`, and other features — but cross-feature access goes **only** through the `@/features/<x>` barrel, never a deep path.
- **`app`** (shell + bridges) may import anything.
- **No import cycles** anywhere under `src/`.
-
-The authoritative rules and rationale live in [`.dependency-cruiser.cjs`](.dependency-cruiser.cjs) (its header documents the layers and the known-violation ratchet). Any **new** layering or cycle violation fails the `dependency-cruiser` job and blocks `ci-ok`, so run **`npm run dep:check`** locally before opening a frontend PR. The known-violations baseline in `.dependency-cruiser-known-violations.json` only ratchets **down** — don't regenerate it to silence a new violation; fix the import instead.

 ## CI on pull requests to `main`

 PRs must target `main`. `next` and `release` are maintainer-driven promotion branches — don't target them directly.

 Workflows are path-filtered (see the YAML for exact `paths` / `paths-ignore`):

- **Frontend** (`src/**`, lockfile, Vitest/Vite/tsconfig, ESLint config, dependency-cruiser config, etc.): `npm run lint`, **`npm run dep:check`** (layering + cycle guard), `npm test` (Vitest), `npx tsc --noEmit`, then a coverage run.
+- **Frontend** (`src/**`, lockfile, Vitest/Vite/tsconfig, etc.): `npm test` (Vitest), `npx tsc --noEmit`, then a coverage run.
 - **Rust** (`src-tauri/**`): `cargo test --workspace --all-targets`, `cargo clippy --workspace --all-targets -- -D warnings`, then coverage.

-The **`ci-ok`** job in [`ci-main.yml`](.github/workflows/ci-main.yml) is the merge gate: it waits for every required job above whose path filter matched the PR, and fails if any of them failed or did not finish in time.
-
 Hot-path coverage gates are **required** on pull requests: the `coverage` jobs in [`frontend-tests.yml`](.github/workflows/frontend-tests.yml) and [`rust-tests.yml`](.github/workflows/rust-tests.yml) fail when any listed file drops below the floor. See the headers in [`frontend-hot-path-files.txt`](.github/frontend-hot-path-files.txt) and [`hot-path-files.txt`](.github/hot-path-files.txt) for curation rules and thresholds.

-## 🪐 Orbit — Shared Listening
-
-**Listen together, in sync, over your own server.**
-
-Orbit brings real-time synchronized group listening into Psysonic. Start a session, invite people with a link, and everyone hears the same thing at the same time — with host-controlled playback, a shared queue and guest song suggestions.
-
-The clever part: Orbit rides entirely on **your own Navidrome**. There is no external relay, no third-party service and no extra accounts. The session lives on your server, where it belongs. It is built for real-world music sharing without turning your self-hosted setup into a social-media circus.

-## ⚡ Local Library — Instant, and Almost Offline
-
-**A local index of your whole collection, so the app stays fast no matter what your connection does.**
-
-Psysonic keeps a local library of your collection's metadata right on your machine. Because the app already knows your tracks inside out, browsing, searching and starting playback are instant — even a 500 MB FLAC starts the moment you hit play, because nothing has to be fetched or parsed first.
-
-It also means the connection to your server stops being a bottleneck. Even on a slow, flaky or distant link, Psysonic stays responsive and **behaves almost like an offline player**, whatever the network is doing.
-
-And it's the foundation everything else is built on: the local library is what makes on-device analysis, smart audio and snappy navigation possible in the first place.
-
-## 🧠 On-Device Audio Analysis
-
-**One of the most powerful things Psysonic does — entirely on your own machine.**
-
-Built on top of the local library, Psysonic analyzes your tracks locally — **loudness, waveform and tempo** — with no cloud service and no required server-side plugin. That analysis is what powers content-aware AutoDJ transitions, LUFS-based loudness normalization and playback-speed control.
-
-This is a deep, genuinely useful layer that most clients simply don't have, and because it runs locally, it works exactly the same whether you're fully online or barely connected.
-
-## 🎧 AutoDJ — Content-Aware Crossfade
-
-**A DJ that listens to the music, not a stopwatch.**
-
-Most players do fixed-time crossfade: blend the last N seconds into the next N seconds, dead air and all. AutoDJ uses Psysonic's own audio analysis to **trim the silence at the edges of a track and blend out of the actual music** — for transitions that sound deliberate instead of mechanical. It is a standalone playback mode with smooth skip/interrupt handling and a configurable overlap.
-
-## 🔗 Navidrome-Native, Deeply
-
-**Not a generic Subsonic client wearing a Navidrome hat.**
-
-Psysonic binds Navidrome's native capabilities directly: server-side smart-playlist create/edit, playback reporting and OpenSubsonic capability probing. Most clients in this space stay Subsonic-generic. Psysonic goes deeper, so Navidrome users get the features their server can actually deliver.
-
-## 🎨 Community Theme Store
-
-**A real marketplace for themes — installable and schedulable.**
-
-Beyond a big set of built-in themes, Psysonic has a first-party theme registry: browse community themes, install them in-app, and let the **Theme Scheduler** switch looks automatically between day and night.

-## [1.50.0]
-
-## Highlights
-
-### Multi-library filter — browse across your libraries
-
- The sidebar library picker now supports **multi-select with priority ordering** — browse, search, genres, and album/artist detail views aggregate across the libraries you pick and de-duplicate shared items by priority.
- Cross-library matching normalises names per locale (German ß, Norwegian æ, French œ, Romanian ș/ț, Cyrillic ё/й); CJK titles are matched as-is.
- The Genres page and album browse genre filter list the full catalog on large libraries when **All libraries** is selected.
-
-### Navidrome public share links — listen without logging in
-
- Paste or search a Navidrome **public share** URL (`/share/{id}`) to preview the shared track list, then play the full queue with no server account.
- Share playback stays isolated from your logged-in Navidrome queue — idle server play-queue pull cannot replace a share session while you are connected elsewhere.
- While a share queue is active, **Save Playlist** is hidden in the queue toolbar; **Share** copies the original Navidrome `/share/{id}` page URL.
-
-### Fullscreen player — Minimal, Immersive, and Prism
-
- **Settings → Appearance → Fullscreen player style** now offers three looks: **Minimal** (the current sharp view), **Immersive** (artist photo/backdrop with rail or Apple-style scrolling lyrics), and **Prism** (full-bleed artist backdrop, glass lyrics panel, and a single glass control bar).
- In Immersive, **Show artist photo** and **Photo dimming** are configurable; Prism drives progress and the active lyric line from the cover-derived accent colour.
-
-### Lyrics that follow the singer, word by word
-
- The **Server** lyrics source now highlights lyrics word by word as a track plays, so karaoke sync no longer needs the third-party YouLyPlus backend. It requires Navidrome 0.63 or newer and lyrics that carry word timing (TTML or Enhanced LRC files) — everything else keeps highlighting line by line. The requirements are spelled out under **Settings → Lyrics → Lyrics Sources**.
- Embedded Enhanced LRC no longer prints raw word timing codes in the lyric text; FLAC, Ogg Vorbis, Opus, and Speex files with synced lyrics in the `SYNCEDLYRICS` tag show embedded lyrics again.
-
-### Player bar — build your own, plus shuffle
-
- **Settings → Personalisation → Player bar** now also hides the **stop button** and shows the **album name** under the artist (off by default; clicking it opens the album). Star rating, favourite, love, playback speed, equalizer, and mini player can be **dragged into any order** you like — the section is no longer behind **Advanced**.
- A **shuffle toggle** in the player bar shuffles the queue from the current track onwards while keeping the playing track in place; turning shuffle off restores the original order. It survives restarts and keeps Orbit guests in sync with the host. Hide the button from **Settings → Personalisation → Player bar** if you prefer.
-
-### Track lists — optional album cover thumbnails
-
- Browse and queue track rows can show each track's **album** cover (per-disc art when the album has distinct disc covers).
- **Settings → Appearance** adds separate toggles for queue vs browse tracklists; playlist, Favorites, and album-detail grids gain a flex-resize handle on the title column when covers are shown.
- Album detail pages skip per-row cover thumbs when the album art is already shown above the list.
-
-### Discord — Server cover art without exposing your login
-
- **Settings → Integrations → Discord → Cover art source** includes a **Server** option alongside **None** and **Apple Music**. It resolves artwork through the server's public album image link — never an authenticated URL that could expose your login credentials. Requires a publicly reachable server.
-
-### Artists browse — album artists or track credits
-
- Toggle **Album artists** vs **Track artists** on the Artists page — album mode lists indexed album artists; track mode includes featured and guest performers from the local artist index. The choice persists across restarts like **Show artist images**.
- Artist name search no longer depends on query letter case for Cyrillic and other non-ASCII names when the local library index is enabled.
-
-### Theme Store — what's new on each theme
-
- Each theme card has an expandable **What's new** with per-version release notes from the author — including non-visual fixes.
- Installed themes with an available update now appear at the top of the store list so you do not have to hunt for them.
- **Settings → System → Contributors** lists community theme authors in a **Themes** section alongside app contributors; author names refresh quietly from the store in the background.
-
-### Italian and Bulgarian — now in your language
-
- Psysonic is now available in **Italian (Italiano)** and **Bulgarian (Български)** — pick either from the language menu on the **Settings** and **Login** screens.
-
-### Start minimized to tray
-
- New **Start Minimized to Tray** toggle under **Settings → System → Behavior** — the next cold start keeps the main window hidden and Psysonic runs from the system tray until you show it from the tray icon. Requires **Show Tray Icon**; applies on the next launch only.
- Opening the main window from the tray after a cold start renders the sidebar and main content immediately — including on Linux tiling window managers — instead of leaving them invisible or blank until a restart.
-
-### Square corners — a sharper, boxier look
-
- New **Square Corners** toggle under **Settings → Appearance → Visual Options → Display** strips the rounded corners off cards and cover art across the app — handy when a theme's rounding does not suit your album covers. Off by default; buttons, inputs, and dialogs keep the theme's corners.
-
-## Improved
-
- With **Remember EQ per device** on and **System Default** selected, the equalizer now keys profiles to the active OS default output and switches when that default changes outside the app (Windows sound settings, Stream Deck, PipeWire / `wpctl`, and similar). **Linux:** when PipeWire has already moved the stream to the new default, the device watcher skips a redundant reopen to avoid a post-switch stutter. **Windows:** release builds no longer freeze on the loading splash; audio output devices use stable backend IDs with clearer labels, and device-change detection works again after upgrade.
-
-## Fixed
-
-### Playback and audio
-
- Playing a song from a playlist no longer shows the track's own cover in Now Playing when the album page would show album art — Now Playing consistently uses the album cover.
- ReplayGain applies when stream or queue metadata resolves late; gapless auto-advance no longer leaves the playbar on the previous track.
- Pausing a large queue behind a reverse proxy (e.g. Nginx) no longer snaps playback back to an earlier track — Navidrome saves via POST when supported, and a failed save no longer lets idle auto-pull overwrite your queue.
- Internet Radio equalizer presets and slider changes now apply to live stations — not just library tracks.
-
-### Offline, Now Playing, and Navidrome
-
- Desktop builds no longer get stuck showing "offline" when WebKitGTK leaves `navigator.onLine` at `false` while the server is reachable — the app confirms with a real server probe instead.
- When browsing offline, Artists, Albums, Tracks, and Genres list only content with on-disk bytes — pins, favorites-auto saves, and hot-cache playback — instead of the full server or local index catalog.
-
-### Themes and integrations
-
- Connecting a scrobble service in **Settings → Integrations → Music Network** now shows the underlying error alongside the generic network message, so a bad URL or rejected token is easier to tell apart from a reachability problem on your machine.
- Horizontal album rails in themes with drop shadows no longer clip card shadows at the edges — scroll arrows keep working without theme authors overriding rail overflow.
-
-### Browse and library
-
- Adding tracks to a playlist no longer fails past ~341 songs — writes go to the server in batches, and large-playlist edits are faster.
- Queue rows far from the playing track no longer stay stuck on a "…" placeholder — the queue loads details for whatever you scroll to, in the desktop panel, mobile drawer, and fullscreen **Up next** overlay.
- The year filter on **All Albums** no longer clamps on every keystroke while you type a four-digit year — it commits on blur, Enter, or outside click.
- Starring an album on the detail page fills the heart immediately and keeps it filled after reload; album-level stars and ratings reconcile consistently across browse and Favorites.
- Renamed artists no longer linger as ghost entries that open to "Artist not found"; album artist links and cover tiles in **Random Albums** stay consistent after resync.
- Custom playlist and internet radio covers uploaded in Navidrome show again on cards and detail headers.
- Sorting albums by artist now follows the name shown on each row — featured-guest releases no longer land under the wrong artist in **Artist / Year** order.
-
-### Other
-
- Servers behind a custom HTTP header gate (Cloudflare Access, Pangolin, and similar) now work for the full app — add-server errors stay on the form with a clear reason, browse and detail views load natively behind the gate, streaming and covers carry the header reliably, and returning to a LAN address upgrades the connection automatically when both LAN and public endpoints are configured.
- Modal dialogs now announce their title to screen readers when they open.
- **Windows:** **Who is listening?** no longer shows `psysonic/undefined` as the client id.
-
-
 ## [1.49.0]

 ## Highlights

-### Play queue sync — pick up where you left off on another device
-
- Click the header connection indicator to **pull** the active server's play queue when it differs from yours; a yellow LED shows when browse and playback servers do not match.
- While paused or stopped, **idle auto-pull** checks every 10 seconds and applies server changes when you have been still for 30+ seconds.
- Queue **push** sends only tracks owned by the playback server, so mixed-server queues stay sane when you switch servers.
- Local queue edits while paused are no longer overwritten by auto-pull; pressing **Play** pushes your changes immediately, and the sync LED no longer flashes on every track during normal playback.
- After the last track ends with repeat off, idle pull no longer rewinds to an earlier server position — the queue stays where playback finished.
-
 ### AutoDJ — minimum pauses, maximum music

- New **AutoDJ** mode — a smart crossfade that blends tracks intelligently: it trims dead air, rides natural fades, and keeps handovers musical instead of abrupt. Its own button in the queue toolbar and its own entry under **Settings → Audio**, alongside Crossfade and Gapless — only one at a time. Off by default; classic **Crossfade** is unchanged.
- **Smooth skip** (on by default with AutoDJ) crossfades manual Next/Previous and track picks from where you are listening instead of hard-cutting; the play/pause button pulses while a blend is active.
- Cap how long overlaps may last: **Auto** (content-driven, up to 12 s) or **Limit** (slider 2–30 s) under **Settings → Audio → Track transitions**.
- The last track in the queue plays through to the end instead of being trimmed when nothing follows.
+- New **AutoDJ** mode — a smart crossfade that blends tracks intelligently. Each transition is shaped to fit the music: awkward gaps fade away, handovers feel natural, and you spend less time in silence between songs. It's now its own choice in **Settings → Audio** and its own button in the queue toolbar, sitting alongside Crossfade and Gapless — pick one at a time. Off by default; classic **Crossfade** is unchanged.

 ### Playlist folders — your playlists, organised

 - Folders on the **Playlists** page and in the sidebar keep long lists tidy — group by mood, occasion, or anything you like. Drag playlists in, rename and collapse folders, or choose **Move to folder** from the right-click menu. Switch back to a flat list whenever you prefer.

-### Settings — tidier and easier to scan
-
- Settings are grouped into clear, labelled panels so related options sit together — less hunting around. The **Native Hi-Res Playback** option now explains in plain language what it actually does.
- **Normalization** and **Track transitions** are now their own sections under **Settings → Audio**, and the queue options (display mode, toolbar, and Play-Next order) are gathered into one **Queue Settings** group under **Personalisation**.
-
-### Japanese, Hungarian, and Polish — now in your language
-
- Psysonic is now available in **Japanese (日本語)**, **Hungarian (Magyar)**, and **Polish (Polski)** — pick any of them from the language menu on the **Settings** and **Login** screens.
-
 ### Theme store — spot updates, pick your style

 - Version numbers on store themes and ones you have installed make it obvious when an update is ready.
 - Filter for **animated** or **static** themes only — less scrolling when you already know the look you want.

-### Hi-Res playback — smoother transitions between sample rates
+### Settings — tidier and easier to scan

- Under **Settings → Audio → Native Hi-Res**, choose a **blend rate** (44.1 / 88.2 / 96 kHz) for crossfade, AutoDJ, and gapless when adjacent tracks differ in sample rate — mixed 88.2 ↔ 44.1 kHz handovers no longer tear mid-transition.
+- Settings are grouped into clear, labelled panels so related options sit together — less hunting around. The **Native Hi-Res Playback** option now explains in plain language what it actually does.
+- **Normalization** and **Track transitions** are now their own sections under **Settings → Audio**, and the queue options (display mode, toolbar, and Play-Next order) are gathered into one **Queue Settings** group under **Personalisation**.

-### Artist artwork — richer home, artist, and fullscreen views
+### Japanese — now in your language

- Switch on **External Artwork Scraper** under **Settings → Integrations** to pull artist imagery from fanart.tv: a wide backdrop on the fullscreen player, a banner across the top of the artist page, and now the artist's backdrop behind the home screen's **mainstage** too. Off by default, your Navidrome covers stay in charge, and turning it back off removes the fetched images again.
- Choose which images each place uses as its background, and in what order — drag to reorder or switch a source off — right under the same setting. The mainstage also loads the next backdrops ahead of time so they appear without a blank gap.
+- Psysonic is now available in **Japanese (日本語)** — pick it from the language menu on the **Settings** and **Login** screens.
+
+### Artist artwork — richer artist and fullscreen views
+
+- Switch on **External Artwork Scraper** under **Settings → Integrations** to pull artist imagery from fanart.tv: a wide backdrop on the fullscreen player and a banner across the top of the artist page. Off by default, your Navidrome covers stay in charge, and turning it back off removes the fetched images again.

 ### Equalizer — a profile per output device

- Turn on **Remember EQ per device** under **Settings → Audio** and Psysonic keeps a separate equalizer setup for each output — speakers, headphones, a USB DAC — and switches to the right one automatically when you change devices, including when **System Default** is selected and the OS default output changes outside the app. Off by default.
-
-### Orbit — everyone hears transitions the host chose
-
- In a shared **Orbit** session, the host's crossfade, gapless, or AutoDJ settings — including length and smooth skip — apply to all guests until you leave. Transition controls in **Settings → Audio** and the queue toolbar show as host-controlled while you are a guest.
+- Turn on **Remember EQ per device** under **Settings → Audio** and Psysonic keeps a separate equalizer setup for each output — speakers, headphones, a USB DAC — and switches to the right one automatically when you change devices. Off by default.

 ### Themes — follow your system's light and dark mode

 - The theme scheduler can now match your **system's light/dark setting** instead of a fixed clock: pick a light theme and a dark one, and Psysonic switches along with your OS. Choose **Time of Day** or **System Theme** under **Settings → Themes** — the existing time-based schedule is still there.

-### Servers behind a reverse proxy — custom HTTP headers
-
- Per-server **custom HTTP headers** in **Settings → Servers** for Cloudflare Access, Pangolin, and similar gates — applied to library sync, playback, covers, offline download, and the rest without putting secrets in invite links.
-
-### Album details — every genre, not just the first
-
- Album details now show **all** the genres a release spans: the main genre appears inline with a **+N** chip that opens the full, clickable list, each genre linking to its own page. Genres combine album and track tags and read from the local library index, so they work offline too.
-
-### Compact buttons — switch to icon-only controls
-
- New **Compact buttons** option under **Settings → Appearance** switches the action and toolbar buttons between large labelled buttons and small icon-only ones — across album, artist and playlist headers, the shared browse toolbars, and the Most Played controls. Defaults to large; on phones the album header keeps its large touch targets.
-
-### Playlists — sort by date added
-
- Sort a playlist by **Date added** (newest or oldest first), or by title, artist, album and the other columns, from a new sort dropdown in the playlist toolbar. The Subsonic API has no per-track "added on" date, so this follows the playlist's own order — servers add new tracks at the end, so newest-first puts your latest additions on top.
-
-## Improved
-
- **macOS:** the window's title bar now follows the active theme instead of the grey system bar; the native window buttons stay in place, floating over the themed bar.
- Pressing **Play**, **Shuffle**, or **Add to queue** on a playlist starts playback without reloading the whole page with a spinner — editing the playlist still refreshes the list as before.
- Dragging sidebar items in **Settings → Personalisation → Sidebar** (or long-pressing in the sidebar itself) keeps each item exactly where you release it — no snap-back or off-by-one landing.
-
 ## Fixed

 ### Playback and audio

- **Timeline** mode keeps your session play-history strip when you **Play** an album or playlist; the current track stays pinned at the top, and replaying a history row inserts after the playing track instead of replacing the queue.
 - **Opus/Ogg** tracks no longer fight the seekbar while they are still loading — scrub to where you want to be and keep listening.
- The equalizer preset picker shows the active **AutoEQ** profile name again instead of going blank.
-
-### Offline, Now Playing, and Navidrome
-
- The **Live** listener count in the header stays up to date even when the "Who is listening?" popover is closed.
-
-### Browse and library
-
- Album and artist covers — and the full-size view when you click a cover — open at full resolution again instead of looking soft or small.
- Albums sorted by artist now list each artist's work A–Z by title — no more random order within a name.
- **Artist → Year** keeps artists grouped but walks through their albums chronologically, oldest first.
- Genres with no remaining tracks disappear after you retag and resync the library, without restarting the app.
- The **Artists** A–Z index matches Navidrome ignored articles — **The Beatles** lands under **B**, not **T**.
- **All Albums → Only compilations** and **Favorites** return the albums you expect instead of an empty or partial list.

 ### Player and playlists

 - **Add to playlist** from the player bar adds the song you are hearing, not the whole album.
- On **Favorites**, bulk **Add to playlist** and **Play selected** / **Add selected to queue** act on every checked row.
- **Play Now** on a playlist in the right-click menu starts playback instead of only opening the list.
- Playlists page header buttons wrap on narrow windows instead of clipping off-screen when the queue panel is open.

-### Other
+### Browse and library
+
+- Albums sorted by artist now list each artist's work A–Z by title — no more random order within a name.
+- **Artist → Year** keeps artists grouped but walks through their albums chronologically, oldest first.
+
+### Windows

- **Orbit** sessions stay reliable on long listens — guests keep receiving updates, radio no longer pollutes the shared queue, and opening Psysonic on a second device does not delete a live session elsewhere.
- On the artist page, the header uses the fanart.tv background when no banner is available — the same image the fullscreen player already showed.
 - **Windows:** Previous, Play/Pause, and Next are back when you hover the taskbar icon — and Play/Pause shows whether music is playing or paused.
- **macOS:** the dock icon matches native app sizing instead of looking oversized.
- **Linux:** **Niri** is recognised as a tiling compositor and gets the same custom title bar behaviour as Hyprland and Sway; the "new version available" popup reads clearly on setups where the background blur used to bleed through.
-
-## Under the hood
-
- If a screen hits an unexpected error, the app now shows a small recoverable card (**Try again** / **Reload app**) and keeps playing, instead of the whole window going blank.

Author	SHA1	Message	Date
cucadmuh	6e6006408d	fix(autodj): exclude trim-silence bins from edge span and fade length Edge analysis rounded contentStart/End back to bins, which could land inside trim-silence. With the 5 s trim cap, playback seeks partway through a long digital tail but bins between the seek point and real music were still counted in edge.seconds — empty tail/head time leaked into fade duration. Anchor walks at the first/last audible bin (peak > cut) inside the playback window, skip trim-silence in run/shape collection, and measure plateau only over playable content. Adds contentPlayBinRange() shared with computeWaveformSilence.	2026-06-24 17:42:40 +03:00
cucadmuh	e770656a74	fix(autodj): equal-power edge-mix curve + STANDARD_BLEND floor for hard loud↔loud Linear gain sum dipped in the middle and did not feel like a crossfade even with adequate overlap; legacy main equal-power sin/cos transitions sounded clearly better on hard loud↔loud pairs (stabs, abrupt endings). Engine: replace linear lerp with equal-power power-lerp g(p) = sqrt(start²·(1−p) + end²·p) on both incoming (LinearGainEnvelopeIn) and outgoing (TriggeredFadeOut edge-mix branch). Symmetric 0↔1 matches sin/cos; non-zero endpoints keep scenario A/B. Planner: classify edges as hard/ramp/silent; when both sides are hard, raise transition_dur to at least STANDARD_BLEND_SEC (2 s), capped by sustainable content — ported from main planCrossfadeTransition. Regression tests for stabs at track end and edge kind classification.	2026-06-24 17:34:12 +03:00
cucadmuh	103c84895e	fix(autodj): ride A's own fade-out — span the natural envelope, not just the loud run A track with a recorded fade-out ends inside its quiet tail, so the loud-run walk found zero loud bins at the content boundary and edge.seconds collapsed to min_duration. transition_dur then dropped to ~0.5 s and AutoDJ switched to B only once A had already faded into its quiet zone — no sense of blending. Measure the edge span by case: a hard boundary (at/above threshold) keeps the loud run that gives the engine room to fade; a boundary below threshold (a natural fade-out / fade-in) walks the envelope back to the loud body, so B rises underneath A's own fade (the generalised scenario A the gain model already intends via outgoing_gain_end = 1 - y0). A wholly-quiet/silent edge still falls back to min_duration. Updated edge/plan tests to the corrected spans.	2026-06-24 17:07:58 +03:00
cucadmuh	75b56cdb41	fix(autodj): anchor edge analysis at the content boundary, not the raw edge The edge walk started from bin 0 / bin n-1, so any trimmed leading or trailing silence (very common — the percentile-normalised noise floor maps to bin 8 ≤ cut) stopped the loud run immediately and collapsed every edge to min_duration. transition_dur then degraded to ~0.5 s, so AutoDJ played like gapless with no sense of blending. Walk the loud run from the silence-trimmed content boundary instead (B is already seeked to bStartSec), so the edge reflects the real music approaching the transition. §10.2's "quiet intro → min_duration" still holds for genuinely soft content, which is distinct from trimmed silence.	2026-06-24 16:29:18 +03:00
cucadmuh	cdb22fba8e	docs(changelog): AutoDJ edge-mix entry + peri4ko algorithm credit (PR #1167 ) Credit the edge-mix transition algorithm to Ivan Pelipenko (@peri4ko) in the 1.49.0 changelog and add the algorithm contribution line to his existing credits entry.	2026-06-24 15:51:26 +03:00
cucadmuh	0ea783b395	feat(autodj): waveform edge-mix transitions with linear blend Replace the equal-power sin/cos crossfade on the AutoDJ path with a content-derived linear edge-mix (algorithm by Ivan Pelipenko, @peri4ko). Each track boundary ("edge") is analysed from the cached waveform bins into a duration + clamped linear envelope (un-gamma'd amplitude domain, plateau-relative threshold); at mix time the engine derives linear gain curves for the outgoing/incoming tracks and multiplies + sums samples instead of applying cosine fades. - autodjEdgeMix.ts: pure edge-analysis + planEdgeMix / planEdgeMixForSkip - Rust: AutodjLinearMixParams IPC + LinearGainEnvelopeIn / linear fade-to-hold TriggeredFadeOut, threaded through audio_play + sink swap - Wire planEdgeMix into crossfade preload/cache; playTrack passes the linear-mix plan; manual smooth-skip migrated to planEdgeMixForSkip - Settings: configurable min/max transition length (Auto = unconstrained)	2026-06-24 15:47:00 +03:00
