/**
 * Action sheet - the iOS pattern for a short set of choices the user asked for.
 *
 * Two groups, exactly as Apple describes them: the choices in one rounded
 * card, "Cancel" alone in a second one below it with a gap between. The gap is
 * not decoration - it is what makes Cancel unmistakably the way out rather
 * than one more option in the list.
 *
 * Deliberately identical in geometry to `.sheet` in the panel's
 * audi-dashboard.css, which already implemented this pattern: 10px side
 * margins, 16px corners, 52px minimum row height, one hairline between rows,
 * opaque surface. Two codebases, one look.
 *
 * Use `Sheet` instead when the content is a form rather than a list of
 * choices.
