Frank Stellmacher 5b37ab70f1 perf(tracklist): drop now-playing pulse + EQ-bar animations (#488)
* perf(tracklist): replace animated EQ-bar + active-row pulse with static icon

The currently-playing track in any tracklist (AlbumDetail, ArtistDetail,
PlaylistDetail, Favorites, RandomMix) was rendered with two animations
on top of an already-busy DOM:

- `.track-row.active` ran `track-pulse` 3s opacity 1 → 0.6 → 1 infinite
  on the entire row subtree (title button, several Lucide icons, star
  rating SVGs, hover affordances). Opacity is a compositor property, but
  on WebKitGTK without compositing — Linux + NVIDIA proprietary +
  WEBKIT_DISABLE_COMPOSITING_MODE=1 — every animated row falls back to a
  full software repaint of the subtree per frame.
- The "now playing" indicator in the track-number cell was three
  `<span class="eq-bar">` siblings with `transform: scaleY()` keyframes
  (`eq-bounce`), each on its own delay/duration. Same composite story:
  three software-repainted layers per frame, every frame.

On AlbumDetail (long tracklist + cover-art header background + the
already-running WaveformSeek progress rAF in the player bar) the
combined cost held the WebProcess at ~80 % CPU with 1.2 GB RSS for the
entire duration of playback. CPU dropped immediately on pause/stop;
on Composers / Settings (no track rows) the symptom never appeared.
Profiler confirmed continuous Layout & Rendering work synchronised with
isPlaying, not the canvas itself.

Replace both animations with static visuals:

- `.track-row.active` keeps the `--accent-dim` background, drops the
  pulse animation entirely.
- The "now playing" indicator becomes a single Lucide `AudioLines` icon
  (four vertical bars of different heights — reads as an EQ icon, no
  animation, one SVG per active row instead of three animated spans).
  `.eq-bars` className now only sets the accent colour.

Cleanup: dead `@keyframes track-pulse`, `@keyframes eq-bounce`,
`.eq-bars.paused` rule, plus a duplicate `.eq-bar` block in theme.css
(with a `wave` keyframe that was being shadowed by components.css and
had no other consumers).

No behaviour change beyond removing the animation; the row is still
visibly the active one and the icon still marks the playing track.

Warning

Psysonic is under active development. Bugs and rough edges can happen, and features may change as the project evolves.

What is Psysonic?

Psysonic is a desktop music client for self-hosted music libraries. It is designed for people who want the freedom of their own server without giving up the comfort, polish and speed of a modern music app.

It is built with Rust, Tauri v2 and React, with a strong focus on responsiveness, customization, practical music-library workflows and a user interface that does not require a manual before you can press play.

Psysonic is optimized first and foremost for Navidrome. Other Subsonic-compatible servers can work well too, but advanced features may depend on server-side support.
