   No-JS fallback
   A disclosure menu with no script is a row of dead buttons, so without
   JavaScript the whole nav renders as a plain expanded list: every panel and
   pane in flow, no burger, no flyout. Ugly on purpose, and every destination
   stays reachable. (Crawlers see the links either way -- hidden content is
   still in the DOM and still followed.)

   The rules themselves live in a <noscript> block in render.php, NOT here.
   They used to key off `:not([data-js])`, with view.js adding data-js on
   boot -- which meant the expanded state was the default and every fresh load
   flashed the entire mega menu across the screen until the footer script ran.
   Inverting it costs nothing: the markup already ships collapsed, so the
   default state is now the correct one and only genuinely script-less
   browsers ever see the fallback.
   ========================================================================== */
