- Library store notify() coalesces multiple calls per microtask tick into one subscriber notification
- Search input debounces store propagation by 150ms while keeping instant visual feedback
- Empty search input clears immediately for responsive UX
- Remove eagerFetch() call from LibraryStore constructor
- Add deferEagerFetch() that waits for DOMContentLoaded event
- App shell renders before backend data roundtrips begin
- All 4 data types (tracks, albums, artists, genres) still loaded eagerly
- invalidate() still calls eagerFetch() directly for post-scan refresh
album artist gets populated with artist as fallback (frontend also uses
this as display name fallback for albums). added scroll position
persistence when switching main views. also added frontend cache for
faster switching.
