/* Hard guard: the full-screen mobile menu must be unreachable on

   from a resize that skipped the auto-close listener) — display:none
   removes it from paint entirely, unlike the transform-only hiding
   used below 900px, which previously let it render on top of the
   desktop pill nav and look like a duplicated navigation bar. */
