/* Puntina — stile «quaderno»: carta a quadretti con il margine rosso, tappe come adesivi, percorso a matita,
   missioni sui post-it, menu a linguette, il timbro della maestra quando la risposta è giusta.
   Tema scuro = la lavagna (gesso su verde): segue Windows, oppure si sceglie nell'area genitori.
   I caratteri (Andika per leggere, Caveat Brush per i titoli scritti a mano) sono in font/caratteri.css. */
