- Remove compact player mode (seekable bar inline was undifferentiated
from standard; didn't have voice/chapter/warm-up controls)
- Add 'float' player style: a fixed, draggable mini-overlay positioned
above the bottom mini-bar (bottom-right corner, z-55)
· Seek bar, skip ±15/30s, play/pause, time, speed indicator
· Drag handle (pointer capture) to reposition anywhere on screen
· Animated playing pulse dot in the title row
· Suppresses the standard non-idle inline block when active so
there is no duplicate UI
- PlayerStyle type: 'standard' | 'float' (was 'compact')
- Bump localStorage key to reader_layout_v2 so old 'compact' pref
does not pollute the new default
- Listening tab Style row now shows Standard / Float

/**
|
||
* AudioPlayer — controller component.
|
||
*
|
||
* Does NOT own an <audio> element. Instead it reads/writes `audioStore`,
|
||
* which is shared with the layout's persistent <audio> element so audio
|
||
* survives SvelteKit navigations.
|
||
*
|
||
* ── Play flow ────────────────────────────────────────────────────────────
|
||
* On "Play narration" click / auto-start:
|
||
* 1. Populate store metadata (slug, chapter, titles, voice, speed).
|
||
* 2. If the pre-fetch already landed (nextStatus='prefetched' AND
|
||
* nextChapterPrefetched === chapter), use the cached URL immediately.
|
||
* 3. Otherwise try GET /api/presign/audio — if 200, set audioUrl → layout plays.
|
||
* 4. If 404, POST /api/audio/:slug/:n to generate. Drive pseudo progress bar.
|
||
* On success (200 or 202→done), presign and set audioUrl directly from MinIO.
|
||
*
|
||
* ── Voice selection ──────────────────────────────────────────────────────
|
||
* A "Change voice" panel lets users pick from the available Kokoro voices.
|
||
* Each voice shows a play button that streams a pre-generated sample from
|
||
* MinIO (GET /api/presign/voice-sample?voice=...). Samples are generated
|
||
* server-side via POST /api/audio/voice-samples.
|
||
*
|
||
* Changing voice updates audioStore.voice (saved to settings via layout).
|
||
* The currently loaded chapter audio is NOT re-generated automatically —
|
||
* the new voice takes effect on next "Play narration" click.
|
||
*
|
||
* ── Pre-fetch (immediate + 90% fallback) ────────────────────────────────
|
||
* When autoNext is on, prefetchNext() is called as soon as the current
|
||
* chapter starts playing (via maybeStartPrefetch() at the end of
|
||
* startPlayback()). This gives the maximum lead time for Kokoro to
|
||
* generate the next chapter so the transition is seamless.
|
||
*
|
||
* A $effect also watches currentTime/duration and fires prefetchNext() at
|
||
* the 90% mark as a fallback — covering the case where autoNext was toggled
|
||
* on mid-playback after startPlayback() had already returned.
|
||
* The nextStatus !== 'none' guard prevents double-runs in all cases.
|
||
*
|
||
* prefetchNext():
|
||
* • Calls POST /api/audio for next chapter (sets nextStatus='prefetching')
|
||
* • On success, presigns and stores URL in audioStore.nextAudioUrl
|
||
* (sets nextStatus='prefetched')
|
||
* • On failure, sets nextStatus='failed'
|
||
*
|
||
* ── Auto-next ────────────────────────────────────────────────────────────
|
||
* layout.svelte onended → sets autoStartPending=true → navigates.
|
||
* New chapter's AudioPlayer mounts → sees autoStartPending → startPlayback()
|
||
* which uses the prefetched URL if available.
