// Local Library > Tracks, kiosk body — the second surface the release audit
// reported dead, and for the same reason as Artists: it read the legacy
// `localTracksJson`, which stops being republished once the paged
// `QbzLocalTracks` surface is active (the production default since the native
// model shipped).
//
// It issues NO query of its own. The host's `loadActiveTab` — called on mount
// and on every tab switch — installs the SHARED funnel through
// `tracksSetFilterJson`, exactly as the desktop view does
// (LocalLibraryView.qml:700-707), and that setter is the load. The kiosk never
// hands it a neutral descriptor: the value is the same persisted funnel the
// Full UI reads, so nothing saved from the desktop is erased here.
//
// Everything else is KioskLocalTrackList.
