/**
 * The card dialog: one card, whole, as a read view.
 *
 * Opening, closing, and forgetting which card is open is the whole of it. The page
 * cannot change a card, so this module has no request, no confirmation, no banner and
 * no footer actions — the dialogs it used to fill are gone from the document, and the
 * only way a card changes is a tool.
 *
 * The one thing it must not do is leave a stale panel behind: a dialog the kit closed —
 * `Esc`, a backdrop click, its own close button — forgets `openId`, so the next frame
 * stops filling something nobody can see.
