   QSHD site chrome — header (topbar + nav + mobile drawer), footer, and the
   scroll-reveal / sticky-header helpers. These are template parts (header.php /
   footer.php), not blocks, so this is hand-authored static CSS enqueued on the
   front end only (inc/enqueue.php). Consumes --qs-* tokens from design-system.css.
   Ported from designs/qsha/index.html.
