   Blog dei siti dei clienti (Mod\SiteBlog\PublicView)

   Si carica SOLO nelle pagine del blog e dove c'e' il blocco "Ultimi articoli".
   Usa solo le variabili del tema del sito (colori, raggio, carattere dei titoli):
   il blog deve sembrare una pagina di quel sito. Ogni var() ha un valore di
   riserva, perche' i temi vecchi non dichiarano tutte le variabili.
   Margini e bordi con le proprieta' logiche (inline-start/end): in arabo il
   testo va da destra a sinistra.
