// Cover lightbox — NEW in the Qt port (no Slint counterpart): the album art
// at its best available quality, fitted to the window. Opened by left-click
// on the AlbumView cover or by the cover menu's "View cover" entry.
//
// Shape follows TrackInfoModal: a full-window Popup parented to
// Overlay.overlay, a dim scrim whose click closes, Escape closes. The image
// asks for a decode capped at the window size (sourceSize), so a mega
// variant does not cost a full-res decode to display at ~90% of the window.
