/* ==========================================================================
   School HRMS — design system ("glass / aurora")
   Dark-first; light theme via <html data-theme="light">.
   Also restyles the legacy class names (.card, .btn, .chip, .list-item,
   .badge-*, .sheet-overlay, .tab-btn, .empty-state…) that page scripts
   render, so converted pages keep working without JS changes.
