/* ============================================================
   NOTIFICATION SOUND GRID — v1.9.8 + UX v1.9.9
   Selector visual de tonos agrupados por categoria. Reemplaza
   el dropdown plano anterior por cards con icono, preview inline
   y estado activo con checkmark. Usa design tokens del sistema.

   v1.9.9 — mejoras de escritorio:
   - Panel expandido a 900px cuando se abre la seccion notifications
   - Cards con mas respiracion (minmax 130px en desktop)
   - Headers de categoria con linea divisoria y contador de tonos
