   Un fondo bianco, un inchiostro pieno, un campo verde profondo
   che apre e chiude la pagina. Nessun filetto, nessun riquadro
   contornato, nessuna etichetta maiuscola minuscola: la gerarchia
   la fanno scala, spazio e campo di colore.
   Nessuna risorsa esterna: solo tipi di sistema e disegni inline.
