Tenet is Christopher Nolan's 2020 espionage thriller, shot on 65mm and IMAX by Hoyte van Hoytema across windswept European freeports and bunkers. Its visual language is cold, desaturated slate-blue concrete and brushed steel, organized around a split red/blue inversion logic — red flows forward through time, blue runs inverted.

This design system translates that turnstile symmetry into interface form: a dark slate-blue ground, a disciplined red-versus-blue accent pair, brushed-steel grays, palindromic mirrored typography, and bunker-slab geometry. Every component can hold two states — forward and inverted.
