A Ritual Chamber archival film still: a small institutional workspace under glass, files, terminal, browser pane, skill folders, rollback tags, and permission slips arranged around an empty chair that is already leaving traces. Near-empty institute chamber, hard chiaroscuro, analogue tube-amp warmth; dominant slate grade with one concentrated ultraviolet accent in three small vials on the desk. Cream-and-dark institute tile runs across the far wall. The hexagonal honeycomb lattice is the real floor under the desk; one mis-struck Bureau seal on a folder. Numbered callouts: (1) skill cabinet, (2) permission tag, (3) end-state ledger. One wrong detail: the chair casts two shadows. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
