   BLOG — /blog/ e /blog/<slug>
   File: /css/blog.css

   Si carica DOPO /css/landing.css e ne riusa le variabili di :root e le classi
   di impianto (.header, .container, .btn-primary, .features-grid). Qui c'e'
   solo quello che il blog ha in piu' rispetto alla landing.

   L'header del sito e' sticky: occupa gia' il suo spazio nel flusso, quindi
   nessuna pagina deve compensare con un padding-top da header fisso.
