How It Works

1. Sign in with your Plex account using OAuth
2. The app fetches your full watchlist from Plex
3. Titles are automatically classified as Movies, TV Shows, Anime, or Anime Movies
4. Enable auto-refresh to keep your watchlist up-to-date
5. Switch between light and dark themes based on your preference

Maintenance Notes

• Cached watchlist data renders immediately on app load, then currently airing shows get one background season refresh per authenticated token. This prevents the cache write from retriggering the same Plex children requests indefinitely.
• Persisted watchlist cache lives in IndexedDB because the enriched watchlist is too large for Safari localStorage; small auth/theme preferences still use localStorage. The watchlist hook waits for async IndexedDB hydration before fetching so a valid cache does not race with a network refresh.
• The watchlist cache includes a schema version. Bump or invalidate it when cached record shape changes, especially fields used by filters such as Plex Genre metadata.
• Filter categories are exact and non-overlapping: anime uses Plex genre metadata when available, then falls back to the media type so every title has one category.
• The floating view controls use the round button as the only close affordance while open; outside clicks hit a transparent backdrop that closes the panel without clicking the watchlist underneath.
• The watchlist API is paginated; keep pagination intact so "All" really means the full watchlist.
• Use bun run test, bun run lint, and bun run build before shipping changes.
