/**
 * Single-item "handoff" slot for MetadataScreen. A callsite sets [pending] with the target
 * track just before navigating to the metadata destination; the destination's ViewModel
 * reads it on first load and then clears it.
 *
 * Using this rather than passing the track through the navigation route because [DidlItem]
 * isn't Parcelable and adding kotlin-parcelize for a single transient handoff isn't worth
 * the build-config cost. Single-threaded TV app → no real risk of racing writers.
