/* ============================================================
   ew-mobile-nav.css
   Off-canvas mobile navigation for EW2027.

   Loaded AFTER site.css and calmenu.css so these rules win on
   equal specificity. This file does three things:

     1. Fixes the sub-menu bugs (fixed wide/mega widths and the
        calmenu breakpoint mismatch that overflowed the panel).
     2. Turns the existing stacked hamburger menu into a proper
        slide-out (off-canvas) panel with a backdrop + scroll lock.
     3. Keeps the desktop mega-menu completely untouched.

   No new markup classes required — it reuses .site-nav /
   .nav-toggle / .nav-menu / .nav-list / .nav-item / .nav-link /
   .nav-dropdown and the existing .is-open toggling. One optional
   element (.nav-backdrop) is added by ew-layout.js.

   Breakpoint is unified at 1100px to match site.css. Everything
   below lives inside that one media query so desktop is safe.
