// Mirrors the Svelte AlbumCardLite: 220px column, 220px square artwork
// with a bottom-left award ribbon and a hover overlay (dark scrim,
// genre/year meta, and play / favorite / more action buttons), then a
// tight title / artist stack alongside an icon-only quality badge.
// Deterministic 266px height.
