// Local track row — the SHARED rows/TrackRow.qml with the local arms set,
// plus the three things the shared row has no arm for:
//
//   * the always-visible SOURCE glyph the Slint renders from
//     `show-source: true` (LocalLibraryView.slint:1489) — drawn OUTSIDE the
//     shared row so TrackRow keeps one column layout for every surface;
//   * the multi-select checkbox (Slint TrackRow's `multi-select-mode`
//     swaps the number cell for it) — overlaid on the number cell here for
//     the same reason: no fork of the shared row, no shared-file edit;
//   * the LOCAL context menu.
//
// THE MENU (this is the `force-local-menu` arm of the unified Slint menu —
// TrackRow.slint:68 -> TrackMenuState -> AppShell.slint:1009-1021 ->
// TrackContextMenu.slint). For a local / Plex / offline row on a library
// surface Slint resolves to: qobuz-actions OFF, favorite OFF, Track info OFF
// (show-track-info rides the Qobuz block), mixtape ON, add-to-playlist ON,
// Go to album / Go to artist ON (`local-goto-actions`). So the full local set
// is: Play now, Play next, Play later, Add to queue, Add to mixtape, Add to
// playlist, Go to album, Go to artist.
//
// Add to playlist is LIVE (QbzPlaylistPicker). It goes through
// `QbzLocal.bulkAction("track", [id], "add-to-playlist")` — the LOCAL-mode
// arm — and not through the picker singleton directly, because only
// `local_bulk::resolve_blocking` can turn a Tracks-table row id into the
// `LocalTrack` that `local_picker_ref_for_track` needs; a Plex row's ref is
// "plex:<rating key>" and its numeric display id means a different track the
// moment anything reads it as a catalog id. The bulk entry point takes a JSON
// id array, so a single row is a one-element array — same code path, no
// second resolver.
//
// Add to mixtape rides the SAME entry point for the same reason
// (`local_bulk.rs::apply` "add-to-mixtape" -> `myqbz_add_qt::open_items(
// track_items_from_local(rows))`), which restores the .slint's order:
// Play now · Play next · Play later · Add to queue · Add to mixtape ·
// Add to playlist · Go to album · Go to artist. Every row that IS shown is
// wired; nothing here renders and no-ops.
//
// The shared row's own ⋯ is turned OFF (`showMenu: false`) because its
// entries are the Qobuz set: its Go-to-album/artist call QbzAlbum.openAlbum /
// QbzArtist.openArtist with CATALOG ids, and a local row carries a local
// group key + a bare artist NAME. The button is re-drawn here, in the exact
// same gutter (the shared row is narrowed by precisely the 32px cell + 14px
// gap it no longer draws), and both it and a right-click open this menu.
//
// Artwork follows the Slint gate (AppearanceState.local-library-track-
// artwork, default OFF) — decoding a cover per row is exactly what froze
// this surface at 16k tracks.
