/* ============================================================
   HEADER / NAV — corrected
   FIX: removed the duplicate .dropdown-menu block that was
   appended after the media queries. It re-applied desktop rules
   (opacity:0; visibility:hidden; position:absolute) on mobile,
   making opened dropdowns occupy space but stay invisible.
   Also hardened .dropdown.active .dropdown-menu on mobile.
