/* ============================================================
   Bootstrap 5 layout fallback — grid, flex, navbar, carousel.
   Loads BEFORE the CDN so real Bootstrap overrides it when
   present, but the site lays out correctly if the CDN is
   blocked or slow. Specificity kept flat (single-class) so
   media-query overrides win correctly.
