/* ═══════════════════════════════════════════════════════════════════════════
   Mobile navigation drawer (.sf-mnav) — shared by the public site (menu.ejs,
   variant .sf-mnav--index, always dark) and the portal (mobile-nav.ejs, variant
   .sf-mnav--portal, follows the light / dark theme). Structure and interaction
   follow the accordion pattern of enterprise mobile menus: fixed header, a
   scrolling list of categories that expand in place, and a fixed account area.
   Behaviour lives in /assets/js/sf-mobile-nav.js.
