// PmGridCard — the GRID-mode playlist cell (PlaylistManagerView.slint:470-618).
// 160 wide; 220 tall, or 250 when the reorder header shows. r8, `surface-card`
// → `surface-hover` on BODY hover (the footer buttons are outside the body
// area, exactly like the reference's `ta`), 0.6 opacity while hidden.
//
// Affordances (contract D27): open (body), favourite, visibility,
// edit-playlist, add-to-mixtape, move-up, move-down. NO move-to-folder — that
// one exists only on the list row. The four footer buttons are ALWAYS visible;
// there is no hover reveal, no play affordance, no pin badge and no overlay row
// on this card (that is cards/PlaylistCard.qml, a different component).
//
// TWO local-row suppressions, both contract decisions:
//   * D28 — the cassette is NOT RENDERED on a `local:` row. `accepts_item`
//     answers `Accepts::NONE` for (Playlist, Local) and `qbz_mixtape::enqueue`
//     hard-errors, so the row can never resolve; a dimmed control would promise
//     "temporarily unavailable". `Row` skips invisible children, so the footer
//     simply narrows.
//   * D29 — the reorder chevrons are NOT RENDERED on a `local:` row (custom
//     positions are u64-keyed and `reorder_step` drops locals), but the 22 px
//     header IS still reserved: `canReorder` switches EVERY card 220 → 250
//     globally, so hiding the header would leave a 30 px hole in this one card.
//
// The grip glyph between the chevrons is DECORATIVE — no MouseArea. The
// reference has no drag and drop anywhere in this view (contract D30) and the
// counter row says so in words ("Use the arrows to reorder playlists").
