	 * Words.Drawer — companion right-rail eidos wrapper.
	 *
	 * After HIER-1/2/3 the drawer renders a STACK of panels from
	 * most-specific to most-general. E.g. inside a table cell with
	 * text selected the user sees: Format → Cell → Row → Table —
	 * each panel scoped to its level so every relevant action is
	 * reachable from one surface (instead of guessing which popover/
	 * menu owns it).
	 *
	 * Modes are derived in soma (`WordsDrawerProvider.modes`); eidos
	 * just paints them.
