/* ==========================================================================
   E-Navajyothi design system
   Replaces AdminLTE 3 / Bootstrap 4. Self-contained, no build step.

   It deliberately keeps the Bootstrap class names the page templates already
   use (.card, .row, .col-*, .table, .btn, .form-control, .small-box, .badge,
   .alert) so every existing page inherits the new look, and adds the new
   components the app needs (toolbar, pagination, stat, empty state, chips).
