/* ---------- TITOLI: peso e asse ottico (19-08-2026) ----------
   Newsreader e' un font variabile con DUE assi: il peso e la dimensione ottica (6..72).
   Il browser regola il secondo da solo in base al corpo del testo, quindi piu' il titolo
   e' grande piu' il carattere si assottiglia per conto suo, grazie comprese. Sui corpi
   grandi lo fissiamo a 22: stessa eleganza, ma le aste e le grazie restano piene.
   Attenzione: font-variation-settings ignora font-weight, quindi ogni regola qui sotto
   deve portarsi dietro anche 'wght'.
   Verifica: ?titoli=300 nell'URL rimette l'assetto precedente per il confronto. */
