// Vertical A-Z jump strip (favorites/FavoritesView.slint:398 `AlphaStrip`;
// LocalLibraryView.slint:577 is a 1:1 lift of the same component). 18px
// gutter, 15px rows, 9px semibold muted letters that go accent on hover.
// Emits jump(ordinal, index); the host scrolls its own view — exactly like
// the Slint, which scrolls proportionally on the grouped grids (:1996) and by
// row index on the uniform track list (:1687).
//
// PROMOTED from views/local/AlphaStrip.qml, unchanged except for the import
// depth — same move QbzMultiSelectBar made and for the same reason: the Slint
// component was always shared (Local Library albums/artists/tracks AND the
// Library favorites tabs), so the "local" folder was a naming accident. The
// old views/local/AlphaStrip.qml is GONE; this file is the only copy.
// Call sites: views/local/{LocalAlbumsTab,LocalArtistsTab,LocalTracksTab}.qml,
// views/library/{LibraryAlbumsList}.qml and views/LibraryView.qml.
