/* ---------- Allineamento dei testi ----------
   La giustificazione migliora il testo solo quando la riga supera ~45 caratteri.
   Sotto quella soglia produce buchi di spazio bianco fra le parole.
   Misurazioni reali su questo layout (caratteri per riga):

                 640px   768px   1024px   1280px+
     bio           46      63       32        44
     riquadri      28      37       32        40

   Quindi: giustificati solo i testi lunghi delle schede di presentazione,
   e non fra 1024 e 1279px, dove la griglia a due colonne stringe la colonna
   a 32 caratteri. I riquadri piccoli restano allineati a sinistra: non
   raggiungono mai una larghezza sufficiente.
   Sillabazione italiana attiva (lang="it") per evitare i "fiumi" di bianco. */
