Multi-pronged attempt to fix cumulative lag between audio playback,
now-playing display, and browser notifications:
== Synchronization (work in progress) ==
- Server-side time-based metadata delay via get-listener-now-playing
with configurable *browser-buffer-seconds* parameter
- First track after restart syncs perfectly; subsequent tracks drift
due to browser audio buffer bloat (buffer grows unbounded over time)
- Added client-side buffer bloat detection: monitors audio.buffered
vs audio.currentTime and auto-reconnects when buffer exceeds 15s
- Added [STREAM-SYNC], [NOTIFY], [BUFFER] diagnostic logging to
browser console for ongoing diagnosis
== Countdown timer ==
- Server exposes remaining seconds via pipeline-track-remaining
- now-playing JSON API includes 'remaining' field adjusted for
browser buffer delay
- Player frame shows [mm:ss] countdown next to track title
- Main page now-playing area also shows countdown with its own
polling (15s interval) and local 1-second ticker
- LASS styles for .track-countdown and .track-countdown-mini
== Playback state fix ==
- Fixed save-playback-state saving one track ahead of what was
actually playing (was saving the track loading during crossfade)
- Uses *pending-save-file* with one-track delay so the saved state
reflects the track that was actually heard
== Notifications ==
- All notification conditions working correctly per diagnostic logs
- show-track-notification logs supported/permission/enabled/last/title
- Notifications fire consistently on track changes
- Add user playlist creation, editing, and track management
- Add library browser for adding tracks to playlists
- Add playlist submission workflow for station airing
- Add admin review interface with preview, approve, reject
- Generate M3U files on approval in playlists/user-submissions/
- Include user-submissions in playlist scheduler dropdown
- Use playlist description as PHASE tag in M3U
- Add database migration for user_playlists table
- Update TODO-next-features.org to mark feature complete
- Add user_favorites and listening_history database tables
- Add migration 005-user-favorites-history.sql
- Create user-profile.lisp with favorites/history API endpoints
- Add star button (☆/★) to Now Playing on main page
- Add star button to frame player bar
- Add Favorites section to profile page
- Show login prompt when unauthenticated user clicks star
- Use gold color (#ffcc00) for favorited state (space theme)
- Fix require-authentication to properly detect API routes
- Support title-based favorites (no track DB required)
