- Type `window.__psyHidden` once via global declaration; drop 6 `(window as any)` casts.
- `WindowVisibilityProvider` now ORs `window.__psyHidden` into the hidden state
(and into the initial state). On WebView2 `document.hidden` does not always
flip when `win.hide()` is called, so effects gated by `useWindowVisibility()`
can now actually skip creating intervals/rAF instead of relying solely on the
per-tick fallback check.
- Slow visible-poll from 200 ms to 500 ms (5 → 2 wakeups/s for visibility alone).
- Fix stray leading-space indent in `App.tsx` `window:close-requested` comment.

* fix(windows): stop GPU rendering when windows are hidden
* perf(ui): tighten hidden-window rendering mitigation
Align implementation and documentation with what the injected pause/resume
scripts actually do, reduce main-thread and compositor wakeups while windows
are invisible, and make lifecycle cleanup reliable.
Rust (Tauri)
- Document PAUSE/RESUME as compositor-oriented hints: set __psyHidden, optional
--psy-anim-speed for CSS that opts in, and pause @keyframes via
animation-play-state only (not CSS transitions, not arbitrary timers or rAF).
- Walk descendants under #root instead of document-wide querySelectorAll('*')
to cut cost on large pages; skip the walk if #root is missing (flag still set).
- Call eval(PAUSE_RENDERING_JS) before hide() on all hide paths (tray menu,
tray icon toggle, mini open/close/show-main, native mini close) so the
webview sees __psyHidden while still fully schedulable.
- Shorten pause_rendering command rustdoc to match the script.
Frontend
- WindowVisibilityProvider: replace self-rescheduling useCallback with a single
effect that keeps one pending timeout id, uses a cancelled flag on unmount,
and syncs hiddenRef from document.hidden at mount (no orphaned timers after
tests/HMR).
- WaveformSeek (preview + animated seekbar): while hidden, poll with a 400 ms
timeout instead of requestAnimationFrame every frame; cancel both rAF and
timeout on teardown.
Why
- Accurate comments prevent future refactors from assuming “full JS idle”.
- Smaller DOM walks and fewer rAF wakeups reduce spikes when hiding the main
window or mini player on Windows WebView2 and elsewhere.
* perf(ui): pause global CSS + timers when Tauri hides the window
Builds on PR #273 (`7803d8e` + `0e07a73`). Adds a second HTML flag driven only by
Rust pause/resume inject so infinite animations still pause when WebView2 keeps
`document.hidden === false` after `win.hide()`, and stops a few periodic JS
timers while the window is invisible.
- `lib.rs`: set/remove `data-psy-native-hidden` on `<html>` in PAUSE/RESUME JS;
document why in rustdoc (rest of pause/resume unchanged from PR tip).
- `components.css`: same `animation-play-state: paused !important` rules as
`data-app-hidden` for `[data-psy-native-hidden="true"]`; refresh the comment.
- `App.tsx`: comment distinguishes tab visibility vs Tauri-native hide.
- `Hero.tsx`: do not run the 10 s carousel interval while hidden
(`useWindowVisibility` + `__psyHidden` in tick).
- `PlaybackScheduleBadge.tsx`, `playbackScheduleFormat.ts`: no 400/500 ms
intervals while hidden; skip ticks when `document.hidden` or `__psyHidden`.
