Major version bumps (riverpod 2->3, go_router 14->17, just_audio 0.9->0.10, flutter_secure_storage 9->10, google_fonts 6->8, flutter_lints 4->6). package_info_plus held at 8.x due to win32 conflict with secure_storage 10.x. Riverpod 3 breaks: AsyncValue.valueOrNull -> .value, StateProvider replaced with Notifier subclass. just_audio 0.10: ConcatenatingAudioSource -> setAudioSources. Search slice: - models/page.dart (generic Page<T> envelope) - models/search_response.dart (3-facet wrapper) - api/endpoints/search.dart - search/search_provider.dart (debounced 250ms) - search/search_screen.dart (TextField + 3 horizontal/vertical sections) - Wired /search route + search button on home AppBar
