   Mobile(<=880px): submenu static nested in the drawer (all touch phones).
   Touch >=881px (no hover): degrades gracefully — parent link goes to the section index page.
   Close is INSTANT (visibility never transitioned -> no focusable-but-invisible window).
   Motion gated at source (reduced-motion users get no transform). dek folded into each sub-link aria-label. */
