- **Artist Data & Metadata**:
    - Integrates `ArtistImageRepository` into `MusicRepositoryImpl` to support artist image retrieval.
    - Enhances `getArtists` to combine MediaStore song data with cached database artists, enabling the display of remote artist images.
    - Implements an asynchronous prefetch mechanism in `MusicRepositoryImpl` to fetch missing artist images without blocking the UI.
    - Updates `ArtistImageRepository` with a `failedFetches` cache to prevent redundant API calls for non-existent artist images and improved error handling for timeouts.

- **Theming & UI**:
    - Adds a `contrastColor` utility to `GenreColors.kt` to dynamically determine the best text color (black/white) based on background luminance, improving accessibility across dynamic genre themes.
    - Updates `GenreDetailScreen` to use the standard `Rounded.Menu` icon for options and cleans up `LocalContentColor` imports.
    - Refines the vector path and attributes for `rounded_menu_24.xml` for better visual consistency.
    - Adds `rounded_bottom_drawer_24.xml` vector resource.

- **Dependency Injection**:
    - Updates `AppModule` to provide `ArtistImageRepository` to `MusicRepositoryImpl`.
