/* ===========================================================================
   FAQ page, design canvas "QMS - FAQ" (2026-11-02)
   ===========================================================================
   Loaded only on pages whose content uses the `cq-faq-` sections (see
   inc/page-faq.php). Values follow the canvas and the Certain QMS Web Design
   System it was built with: white hero with breadcrumb, title and lead, then a
   category sidebar beside the question groups. Each question is a native
   <details> (one open at a time per group through its shared `name`), so the
   page works without script. Breakpoints as on the other canvas pages:
   tablet below 1024px, phone below 600px.

   assets/js/page-faq.js marks the category in view and, below 1024px, turns
   the category list into a dropdown under a button. It also adds the search
   field above the categories and the "expand all" button above the groups.
   Without script the list shows as a plain list above the questions.

   Spacing comes from flex/grid `gap`, so block margins inside these sections
   are reset, as on the configuration page. */
