   PISCO FACTORY — sito a tutto schermo
   Token system: chassis scuro caldo, due canali con l'accento reale delle
   rispettive app (Sonora #ff3b5c, Bassmate #22e0d6). Il linguaggio resta
   quello di un rack audio (canali, jack, VU meter) ma senza cornice: le
   sezioni corrono da bordo a bordo dello schermo, senza pannello né viti.
