   AN CREATIONS — Sitio v4
   ------------------------------------------------------------
   CONCEPTO: "El estudio y la noche".
   La página alterna entre los dos mundos de Arturo:
     · CLARO (hueso)  = el estudio, el papel, el orden.
                        Ahí va la información.
     · OSCURO (negro) = la noche, el bar, el escenario.
                        Ahí va el trabajo.
   La alternancia es la firma. Nada más grita.

   Paleta y tipografía: las de la marca (Identidad Visual).
   No se usan #000000 ni #ffffff puros.
