/* Collapsed state is controlled purely by JS via data-collapsed, at
   every screen width — it defaults open on tablet/desktop (≥768px) and
   closed on mobile (see toc.js), but stays toggleable everywhere. A
   width-based override here previously forced the list open on desktop
   regardless of data-collapsed, so the toggle button looked interactive
   but didn't actually collapse anything above 768px. */
