  The frosted-glass background lives on ::before, not on .site-header
  itself. backdrop-filter (like transform/filter) turns the element it's
  set on into the "containing block" for any position:fixed descendant —
  so with it set directly on .site-header, the mobile nav panel nested
  inside would size itself against the header's own 76px-tall box instead
  of the real viewport (the bug behind the menu rendering half-covered
  with page text showing through it). Isolating the blur to a decorative
  ::before layer keeps .site-header itself free of that property, so the
  nested fixed nav panel correctly sizes against the full viewport again.
