Ritual Chamber analogue silver-gelatin film still: a single black-brass decision clock with one recessed action button rests on a cream plinth in a near-empty institute chamber. A gloved hand hovers beside it without pressing. The floor is a real hexagonal lattice; deep walls carry the interlocking cream-and-dark institute tile. One short line of phosphor-green vials supplies the only colour accent. High oblique camera, hard warm key light, silent near-black shadow. Numbered callouts mark 01 action button, 03 context relay, and 06 restraint spring. A small circular Bureau seal is struck once below. The clock face displays tomorrow twice.
