/* ============================================
   BOOTSTRAP COMPATIBILITY CSS

   Minimal replacement for Bootstrap 5 utility classes
   still referenced by migrated pages. MudBlazor provides
   most layout/spacing/flex utilities (d-flex, me-2, mb-3,
   gap-*, overflow-*, etc.) so only non-MudBlazor classes
   are included here.

   Created during Phase 7 (Bootstrap Cleanup) of MudBlazor migration.
