  "input": {
    "prompt": " Photo-style illustration of an empty government corridor in a sleek sci‑fi capitol building, shot in one-point perspective, where hundreds of traffic cones have appeared in meticulous rows overnight. Include a small cleaning droid paused mid-buff, a lone security guard holding a clipboard, and a “Wet Floor” sign dwarfed by cones. Lighting: cold fluorescent, early-morning hush; mood: baffled bureaucracy."
