/**
 * The context menu on a release card on the artist page.
 *
 * The page already had one, for the top *tracks*, and the release cards
 * — which are most of the page — had none: a right-click did whatever
 * the browser does and the keyboard had no way in at all.
 *
 * What is worth pinning is not that the menu opens. It is that the
 * items shown match what the release can actually do, because the three
 * cases genuinely differ: an owned release has files to queue, an
 * unowned catalog release has nothing to play but can be requested, and
 * a library-only release has no catalog id, so it can be played and is
 * the one case with nothing to view upstream. A menu that offers Play
 * on a release with no files is the fault `library-status-indicator`
 * was rewritten to stop making, one control over.
