Tabs get a sliding indicator that persists across library routes, grid rows flip and collapse on removal, the selection bar and filters crossfade, album tracks move between lists with a crossfade, processing badges pulse and the dropzone scales while dragging.
Use type recipes and Button danger variant, add danger tint, dropzone and cover-fill tokens, give SearchInput a size prop so the top bar keeps its larger search, show queue details inline on mobile, derive upload limits from constants and document the card hover style.
Track lists and the upload queue now render through a declarative DataGrid, the album editor reuses AlbumForm with a split layout and a track picker, and genre labels and types are shared helpers.
