/* =====================================================================
   IMPACTIA — Interfaz v2 («llamativa con degradados»)
   Capa visual sobre styles.css: no cambia la estructura, solo el aspecto.
   · Degradado de marca azul → violeta → magenta para lo activo y las acciones.
   · Fondos con halos de color, tarjetas con borde luminoso y más aire.
   · Vale para modo oscuro y claro; respeta «reducir movimiento».
