   NOTA IMPORTANTE sulla tipografia: subpage.css stila la prose con il
   combinatore figlio (`.content-block > h2`, `> p`, `> ul`…). Qui si
   completa quello che manca usando LO STESSO schema: il corpo dell'articolo
   deve restare figlio diretto di .content-block, senza wrapper, altrimenti
   tutta la tipografia smette di applicarsi.
