**Profile stats tab**
- New Stats tab on /profile page (Profile / Stats switcher)
- Reading overview: chapters read, completed, reading, plan-to-read counts
- Activity cards: day streak + avg rating given
- Favourite genres (top 3 by frequency across library/progress)
- getUserStats() in pocketbase.ts — computes streak, shelf counts, genre freq
**Discover history tab**
- New History tab on /discover with full voted-book list
- Per-entry: cover thumbnail, title link, author, action label (Liked/Skipped/etc.)
- Undo button: optimistic update + DELETE /api/discover/vote?slug=...
- Clear all history button; tab shows vote count badge
- getVotedBooks(), undoDiscoveryVote() in pocketbase.ts
**Rating-ranked discovery deck**
- getBooksForDiscovery now sorts by community avg rating before returning
- Tier-based shuffle: books within the same ±0.5 star bucket are still randomised
- Higher-rated books surface earlier without making the deck fully deterministic
**End-of-chapter sleep timer**
- New cycle option: Off → End of Chapter → 15m → 30m → 45m → 60m → Off
- sleepAfterChapter flag in AudioStore; layout handles it in onended (skips auto-next)
- Button shows "End Ch." label when active in this mode

- Store cover and chapters array in audioStore (populated by AudioPlayer on startPlayback)
- Page server returns full chapters list on normal path; empty array on preview
- Mini-bar: replace arrow link with book cover thumbnail (fallback book icon)
- Mini-bar track info area is now a button that toggles a chapter list drawer
- Chapter drawer slides up above the mini-bar, lists all chapters with current one highlighted
The boolean flag was set by onended before goto() resolved, causing the
still-mounted outgoing chapter's AudioPlayer $effect to fire and call
startPlayback() for the wrong (old) chapter — restarting it from scratch.
Replace with autoStartChapter (number | null): the AudioPlayer only acts
when its own chapter prop === autoStartChapter, so the outgoing component
never matches and the incoming one fires exactly once on mount.
- Add NextStatus type and prefetch state (nextStatus, nextAudioUrl, nextProgress, nextChapterPrefetched) to AudioStore
- AudioPlayer triggers prefetchNext() when currentTime/duration >= 0.9, autoNext is on, and a next chapter exists
- startPlayback() uses the pre-fetched URL if available (skipping presign round-trip and generation wait)
- Auto-next button in layout shows a pulsing dot while prefetching and a green dot when ready
- AudioPlayer shows inline prefetch progress and ready state below the controls
- Fix indentation regression in layout onended handler
When autoNext is enabled, audio automatically advances to the next chapter
when a track ends — navigating the page and starting the new chapter's audio.
- audioStore: add autoNext (toggle flag), nextChapter (written by AudioPlayer),
and autoStartPending (set before goto, cleared after auto-start fires)
- layout: update onended to call goto() and set autoStartPending when autoNext
is on and nextChapter is available; add auto-next toggle button to mini-player
bar (double-chevron icon, amber when active)
- AudioPlayer: accept nextChapter prop; write it to audioStore via $effect;
auto-start playback when autoStartPending is set on component mount; show
inline 'Auto' toggle button in ready controls when a next chapter exists
- Chapter page: pass data.next as nextChapter prop to AudioPlayer
- Add audio.svelte.ts: module singleton AudioStore (Svelte 5 runes) with
slug/chapter/title metadata, status, progress, playback state, and
toggleRequest/seekRequest signals for layout<->audio element communication
- Rewrite AudioPlayer.svelte as a store controller: no <audio> element owned;
drives audioStore for presign->generate->play flow; shows inline controls
when current chapter is active, 'Now playing / Load this chapter' banner
when a different chapter is playing
- Update +layout.svelte: single persistent <audio> outside {#key} block so
it never unmounts on navigation; effects to load URL, sync speed, handle
toggle/seek requests; fixed bottom mini-player bar with seek, skip 15s/30s,
speed cycle, go-to-chapter link, dismiss; pb-24 padding when active
- Pass chapterTitle and bookTitle from chapter page to AudioPlayer
