   Misma estética que el resto del sitio: banda oscura de cabecera
   (el patrón .cat-hero que ya usan categorías y comparativas) y
   contenido claro debajo. Nada de páginas enteras en negro: el salto
   de blanco en comparativas a negro en herramientas se nota y queda mal.

   Un solo color —el azul de marca— modulado por tonalidad y sombra.
   Ni verdes, ni limas, ni ámbares.
