   Gestaltung: Cyanotypie — Preußischblau als Trägerton, Bernstein als
   Signalfarbe (das Sicherheitslicht der Dunkelkammer). Kein Serifen-Display,
   stattdessen eine eng gesetzte Groteske für Überschriften und Monospace
   überall dort, wo Maschinendaten stehen: Schlüssel, Fingerabdrücke, Chiffren.
   Das wiederkehrende Motiv ist das Siegel — das aus dem Schlüssel abgeleitete
   Emblem, das an jeder Identität hängt.
