   Thèse visuelle : le site est un appareil de mesure. Il sépare deux signaux.
   Cyan = signal humain. Ambre = signal synthétique. Ces deux teintes ne sont
   jamais décoratives : elles portent la seule distinction qui compte.

   Monde visuel unique et assumé (console sombre). Pas de thème clair : le
   sujet, la marque et l'instrument ne vivent que sur fond noir.
