HoneyandClaude Opus 4.8 c5649ac22f docs: record 1.1 hard-won knowledge in CLAUDE.md; refresh README
CLAUDE.md:
- Download pipeline: leading aesthetic characters in artist names must be trimmed
  before the iTunes lookup (a missed match cascades into a wrong-duration YouTube
  grab), and an album tag is always written (defaulting to Singles) so Navidrome
  and the metadata editor agree.
- New Android section covering the traps this release cost the most time on: a
  BackHandler inside a NavHost destination loses back priority (overlay back must
  be registered at the app root), overlay state must live in the ViewModel rather
  than remember/rememberSaveable, bottomBar and ModalBottomSheet inset handling,
  reusing the Ktor client, global optimistic StarState, and iTunes artists having
  no artwork.

README: offline downloads also cover single songs and work without a server
connection; StarState added to the data/ listing.

# NovaSonic
A self-hosted music streaming PWA and Android app for Navidrome / Subsonic-compatible servers.
Built with Vite + vanilla ES modules (web) and Jetpack Compose + Media3/ExoPlayer (Android).
---
## Features
- **Library** — Stream from Navidrome / Subsonic; browse artists, albums, playlists, genres, starred, and random; search; star + context menu on every row.
- **Playback** — Queue with shuffle, repeat, and radio mode (endless similar songs); gapless-style preload; lock-screen / notification controls; Navidrome scrobbling.
- **Lyrics** — Synced and plain lyrics via lrclib.net, auto-fetched and cached per session.
- **Artist pages** — Hero card, Last.fm bio / similar / top songs, Ticketmaster events, and iTunes cross-reference showing owned vs. missing tracks.
- **Playlists** — Create, rename, delete, add/remove tracks, and upload a cover (Web + Android).
- **Importer & downloads** — Paste a Spotify / YouTube / YouTube Music / SoundCloud link to download via yt-dlp, with iTunes metadata enrichment and duplicate detection.
- **Metadata editor** (web) — Edit tags + cover art; files are renamed/moved and Navidrome is rescanned on save.
- **Offline** (Android) — Download albums, playlists, or single songs to private storage; an Offline tab to play and manage them (works without a server connection); downloaded tracks play from disk on every screen.
- **Audiobookshelf** — Browse and stream audiobooks with chapter navigation, speed control, sleep timer, and progress sync.
Web is an installable PWA (themes, German UI); Android is native Jetpack Compose + Media3/ExoPlayer with a mini player, media/ABS notifications, and Android Auto. See [CHANGELOG.md](CHANGELOG.md) for the full web/Android parity matrix.
