/*
THESIS: il dato misurato apre ogni superficie; il portale di icone decorative è l’anti-modello.
OWN-WORLD: inchiostro del Golfo, carta fredda, segnale marino, righe da bollettino e numeri pieni.
STORY: leggere valore, unità, età e fonte; poi passare a previsione, radar e archivio.
FIRST VIEWPORT: navigazione compatta, luogo e rete, misura dominante, provenienza nello stesso campo.
FORM: “Bollettino del Golfo”, direzione fissata dal brief e costruita in modalità Operate/Read.
