A Ritual Chamber film still: a driverless car sits motionless in a vast institute hall staged as a blacked-out intersection, hazard lights the single ultraviolet accent. Hard chiaroscuro, silver-gelatin clarity, deep shadow and cream institute tile on the walls. A real hexagonal floor lattice guides silent traffic arrows around the stopped object. Robed backs observe from the margin; one used bandage lies on the polished floor. Numbered callouts: (1) remote confirmation thread, (2) four-way stop ritual, (3) trust leak. Bureau seal struck once, thin filing pointers, no faces. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
