/* ============================================================
   SAZA PERU - enhancements.css
   ÚNICAMENTE las mejoras de UX permitidas por el brief:
   - focus visible / accesibilidad (sin tocar la paleta aprobada)
   - skeletons y empty states donde no existían
   - feedback de formularios (fade del mensaje de éxito)
   - respeto a prefers-reduced-motion
   No altera layout, colores, tipografías ni tamaños del diseño base.
