/* ── MOBILE NAV PANEL ────────────────────────────────────────── */
/*
  FILE GUIDE: mobile-nav-responsive.css

  What this controls:
  - Mobile menu, hamburger, mobile nav curtain, and broad small-screen layout fixes.
  - Some mobile overrides for heroes/nav live here because they interact with the global header.

  How to change it:
  - Change mobile nav open/close layout here.
  - If changing only one page section on mobile, prefer css/responsive/division-pages.css or that page file.
