// Albums tab body (LocalLibraryView.slint:1133).
//
// States, in the Slint's own order: initial spinner, load error + Retry,
// "nothing indexed yet", "nothing matches" (search OR the quality/format/
// source filter emptied the visible set), then the chunked collection with
// the bulk bar and the A-Z jump strip.
//
// Deviation: the Slint scrolls its MultiSelectBar away with the grid (it
// lives inside the scrolling page); here the bar is pinned above the
// collection, because the collection IS the scrolling view (one windowing
// ListView) rather than a page inside a Flickable.
