// AlbumListRow — primitives/AlbumListRow.slint:129+, the LIST arm of a
// CATALOG album collection (Discover Browse, Label Releases). 64px
// (`list-row-h`, DiscoverBrowseView.slint:29), radius 8, odd-row zebra,
// hover surface-hover — coherent with TrackRow.
//
// The local twin is views/local/LocalAlbumRow.qml (56px, local actions, a
// host-owned skeleton). This one is Qobuz-wired: the body opens the catalog
// album, and the ⋯ menu carries the five entries the Slint always shows
// (Open album / Play / Play next / Play later / Add to queue). Right-clicking
// the row opens the same menu at the pointer, like every other ⋯ site.
//
// "Block this album" is the sixth entry, live since QbzBlacklist landed
// (primitives/AlbumListRow.slint:434-441). It is pushed conditionally rather
// than sitting in the literal because the .slint gates it on a non-local /
// non-plex source — see the `entries` block.
//
// item contract: home_qt::HomeCard — { id, title, artist, artistId, year,
// qualityTier, qualityDetail, artUrl, artPath }. `artUrl` is the REMOTE cover
// url and `artPath` the local file:// cache path; only the former may be
// persisted (src/home_qt.rs:117-121).
