   Sistema: papel cálido, tinta casi negra y el cian del isotipo.
   Dos temas con :root[data-theme]: claro (por defecto) y oscuro.
   Lo que mostramos como producto (demos, brief, capas de la portada)
   va oscuro en los dos, como una pantalla.
   Tipografía: IBM Plex Mono para todos los títulos y etiquetas,
   Geist para párrafos. Nunito queda solo en el logotipo.
   Firma visual: tres esquinas pequeñas y una grande (abajo a la
   derecha), igual que la hoja del logo.
