/* ==========================================================================
   Bootstrap 4 → 5 compatibility layer
   Restyles Bootstrap 4 markup that is still emitted by:
     - templates not yet migrated (they extend dashboard/main.html or are standalone pages),
     - crispy-forms' bootstrap4 template pack (CRISPY_TEMPLATE_PACK = 'bootstrap4'),
     - HTML built in Python views for DataTables rows (badge-*, btn-xs, data-toggle…).
   The matching data-* attribute bridge lives in static/js/app.js.

   Every token has a literal fallback so this file also works on standalone pages
   (login, register, password) that do not load app.css.
   Delete this file once no template, crispy pack or view emits Bootstrap 4 classes.
