     MOBILE NAV (drawer) — IMPORTANT
     -------------------------------------------------------
     `header.site` uses `backdrop-filter: blur(...)`, which
     per CSS spec creates a containing block for `position: fixed`
     descendants. If `nav.site-nav` stays inside the header,
     its `position: fixed` is contained by the header box
     (~60px tall), so the drawer renders as a thin sliver.
     Fix: JS relocates `nav.site-nav` to be a direct child of
     <body> on mobile, then these styles position it against
     the viewport correctly.
