/* QA FIX: was a bare `nav` element selector, which matches EVERY <nav> tag
   on the page — not just this one. That silently forced position:fixed;
   top:0;left:0;right:0 onto the footer's <nav class="ft-col"> sitemap
   columns and the mega-panel's internal <nav class="mega-cats">/
   <nav class="mega-simple-grid"> (neither sets its own `position`, so they
   inherited this rule by default), pinning footer link text to the top of
   the viewport on every page. Scoped to the #nav id so only the real site
   header is ever affected. */

     The background is already ~98% opaque so the blur added negligible

     high z-index is a known trigger for GPU layer/compositing bugs at
