   17-blog.css, @layer blog
   Pagine del blog: elenco (/blog) e articolo (/blog/<slug>). Caricato solo
   dai template del blog, dopo la stessa catena CSS della home, con il body
   che porta .c-definitiva .c-blog: eredita carta, inchiostro, header e
   footer della home senza toccare i file condivisi.

   La pagina e' un momento di lettura: una colonna sola a 720px, niente
   isole di tono, niente card. L'ambra compare dove c'e' un'informazione
   (occhiello, link, bottone), piatta.
