   PRB Base - Blog: listados, entrada individual y paginacion

   Solo se carga en contextos de blog: entradas, home de entradas, archivos
   y busqueda. Lo que tambien usan las paginas o el 404 (migas de pan,
   cabeceras, buscador, 404) vive en content.css, no aqui.

   Mobile first. Todas las media queries son min-width.
