Menu
A keyboard-navigable action menu rendered in the top layer (via Popup, so it
flips vs the viewport and is never clipped). Takes the shared size + variant axes.
Variant
A variant re-points --ui-accent (via .ui-accent), so
the highlighted item tints with that colour. Pick one, then open the menu:
Size
size scales the item padding, text, and icons (sm / md / lg).
