qbz/crates/qbz-qt/qml/immersive/ImmersiveSongCard.qml

// ImmersiveSongCard — the minimal bottom-right metadata card (§6.7 of the
// 2026-08-02 immersive-port contract), port of
// crates/qbz-ui/ui/immersive/ImmersiveSongCard.slint:15-114 (divergence D6:
// built fresh — shell/SongCard.qml is the bar's INTERACTIVE meta-link card
// with AudioStamp; this twin is NON-interactive with the E chip).
//
// Mounted by ImmersiveView as layer 4: visible ONLY
// `viewMode==0 && mode==6 && npHasTrack` (trap 19), bottom-right 24px
// insets, and it does NOT fade with the auto-hide chrome
// (ImmersiveView.slint:1602-1605). Content-sized: the card hugs its content
// and the mount pins it bottom-right, so a wider card grows LEFTWARD.
//
//   meta column (right-aligned): title 15px semibold capped 420px + elide
//     (:33-45) + "E" explicit chip 16px (:47-60); subline album italic ·
//     artist 12px, NEVER truncated (:63-84); QualityBadgeFull showIcon:true
//     (:89-93).
//   cover thumb (RIGHT): 72x72 radius 6, shadow 16/#00000080/4 (:97-105).
//
// EXPLICIT SOURCE: Slint reads NowPlayingState.explicit; QbzPlayer publishes
// NO np_explicit (player_bridge.rs:31-114). The queue document's `current`
// row carries the SAME datum (QueueTrack::parental_warning ->
// queue_qt.rs:47,194), so the chip reads QbzQueue.queueJson with the
// guarded try/catch + track-id guard of PlayerBar.qml's npFavorite/npSource
// (the id guard keeps a stale queue document from lending the PREVIOUS
// track's chip to this one).
