/* ============================================================================
   Bootstrap 4 compatibility layer for Bootstrap 5
   Re-adds the Bootstrap 4 classes that were removed/renamed in Bootstrap 5
   and are still used by this project's templates. Rule bodies are ported
   from the old customized Bootstrap 4.5.2 build (old-bootstrap.min.css) so
   the visuals match the previous version exactly.
   Load AFTER bootstrap.min.css.
