   DESIGN TOKENS — marca "TV Premium"
   Negro profundo + dorado metálico, tomados directo del logo (medalla
   dorada con corona sobre fondo negro). El dorado es el único acento;
   todo lo demás se mantiene sobrio para que ese acento se note.
   Tipografía: stack de sistema (máxima compatibilidad en motores de TV).
   Escala: basada en vw sobre referencia 1920px para que se vea igual
   en 1080p y 4K.
