/* ============================================================================
   Orchid Medical — M3 Components + Legacy Alias Layer (m3-components.css)
   ============================================================================
   Two halves:
   1. m3-* component classes (buttons, fields, chips, cards, dialogs, snackbar,
      tabs, tables, progress...) — the new M3 vocabulary.
   2. Legacy alias layer: every class the existing pages use (.btn, .card,
      .badge, .alert, .auth-*, .stat-*, .modal-*, .data-table, .sidebar-*, ...)
      is re-skinned onto M3 tokens/shapes/state layers so the whole app
      re-skins without touching page markup. style.css still loads FIRST;
      this file overrides its visual layer only.

   Version stamp: bump ?v= in every <head> that links this file when changed.
