   Loaded AFTER vendor/bootstrap/bootstrap.min.css. Replaces the legacy
   style.css / helper.css / plugins.css / animate.css stack entirely.

   Selector specificity note: Bootstrap ships multi-class selectors such as
   .navbar-expand-lg .navbar-nav .nav-link (0,3,0). A single-class override
   loses silently, so local rules that must win repeat enough classes to
   match or beat the library selector instead of relying on source order.
