   El landing tiene su propio styles.css (56 KB, casi todo escena y
   animación). Estas páginas son para LEER y LLENAR, así que llevan
   solo lo necesario, con la misma paleta, las mismas letras y el
   mismo pulso: negro, blanco y luz.

   Lo usan también las páginas del blog, que las sirve seratta-admin
