/* ============================================================
   Revision 2026-07-30c — mobile menu containment fix
   Root cause: backdrop-filter on .site-header makes the header
   the containing block for position:fixed descendants, so the
   nav panel's top/bottom resolved against the 59px header and
   collapsed to a strip. Part 1 moves the frosted layer to a
   pseudo-element (a pseudo has no descendants to capture).
   Part 2 gives the panel dropdown geometry that renders
   correctly even if an engine still traps it.
