/* ============================================================
   SITE-NAV — universal nav + search overlay, shared across every
   static marketing/content page. One source (paired with site-nav.js).
   References each page's existing :root tokens (--brand, --ink, etc.).
   Extracted from the canonical home.html nav so they stay identical.
