Ritual Chamber silver-gelatin film still, 4:5 portrait: a single scientific manuscript rests beneath an inspection lamp on a black-glass lectern, while two gloved hands set a small review cartridge into a brass reader. The near-empty chamber has deep shadow, a hard phosphor-green tube band as the HF-PAPER accent, and large quiet walls carrying an interlocking cream-and-dark institute tile. A hexagonal honeycomb lattice is built into the floor; the Bureau seal is struck once lower right. Numbered callouts mark the evidence tray, reviewer threshold, and uncertainty dial; one immaculate approval stamp is deliberately upside down. Warm analogue grain, no faces.
