   Hero de la portada: «Lo que no se ve también se diseña». Solo afecta al hero:
   la cabecera y las secciones de abajo quedan exactamente como en la web actual.
   Portada crema con el plano escondido debajo (variante «claro»); las variantes
   oscuras «espresso» y «cacao» se conservan por si se quieren recuperar. Todo con prefijo .xd.
