   carries it into a new containing block for any position:fixed
   descendant — and the mobile nav drawer (.nav-links) is fixed and lives
   inside header. That was trapping the drawer inside header's small box
   instead of letting it size/position itself against the real viewport,
   which is why it only slid in partway. Keeping the blur on a separate
   ::before pseudo-element (which has no descendants of its own) gives the
