/* ============================================================
   Mobile-safe multi-level menu override (navbar-responsive)
   - Leaves desktop hover menus untouched (>=992px)
   - Replaces bootsnav off-canvas flyouts on mobile with an
     inline accordion: tap L1 -> L2 expands, tap L2 -> L3 expands.
   - Pure CSS + one enhancement script (mobile-nav.js).
   Breakpoint unified to 991px (matches bootsnav.js).
