   Header
   IMPORTANT: .site-header itself must never receive filter/backdrop-filter/
   transform, because .main-navigation (mobile slide-out) and .nav-overlay
   are position:fixed DESCENDANTS of it. Any filter on an ANCESTOR of a
   fixed element becomes its containing block and breaks full-screen
   positioning on mobile. Instead, the frosted look comes from
   .header-glass-bg, an absolutely-positioned sibling layer that carries
   the blur — it is not an ancestor of the fixed nav, so nothing breaks.
