/**
 * The standalone popover surface of the dropdown — a `surface-container-lowest`
 * card at `radius-md`/elevation-2 holding a 4px-padded stack of 48px rows (icon,
 * label, optional inline supporting text). It serves two ARIA contracts: an
 * action `menu` (rows are `menuitem`s) and a select `listbox` (rows are
 * `option`s with `aria-selected`).
 *
 * The consumer owns visibility and positioning (render it inline, or inside a
 * CDK overlay). `compsych-dropdown` composes the same visual language for the
 * panel it opens; this component exposes it for standalone action menus.
