A near-black silver-gelatin Ritual Chamber production still, 4:5 portrait: a tall cream evidence cabinet stands alone in a slate institute chamber, holding three grey activity tablets and one sealed black surveillance reel. Thin phosphor-green threads travel from a keyboard, a window grid, and a task receipt into the cabinet; every source is physically pinned to a low hex-lattice floor. Hard side light, enormous empty walls, and an interlocking cream-and-dark institute tile high above. Numbered callouts mark the replay tablet, privacy seal, and bounded access valve. A small analogue clock in the corner runs backward. One Bureau seal struck once, lower corner. No readable caption text. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
