   Sistema de diseño en tres capas (primitive → semantic → component),
   siguiendo la metodología ui-ux-pro-max.

   Identidad: Personal (Telecom Argentina). La línea cromática de Personal es
   el CELESTE / CIAN. Se usa un cian vivo como color primario, azul noche como
   tinta, y neutros fríos. Pensado para una persona de negocio: lenguaje claro,
   foco en los números, navegación tipo aplicación. Soporta modo claro/oscuro.
