For the door: the proofs were shot by the workshop's own harness driving a headless Chromium, the only browser that touched the page. The composed stills were laid out with Pillow. The four portraits in the long table's tile are that exhibit's own, rendered earlier by FLUX.2 klein 4B (Apache 2.0) through ComfyUI, cel-shaded, and carry no metadata; the Beat Lab's sleeve and the print lab's wall picture were painted by the same model on the workshop's machines, under the same licence, read off each exhibit's own record. The glacier is a photograph by Diego Delso, CC BY-SA 4.0, via Wikimedia Commons, cropped and credited on the door. The layouts were built and audited by AI agents working in lanes; the humans chose the grid, read the proofs, picked the pictures, and signed it.",
