    "prompt": "Use Reference Image 1 only for the copper humanoid robot's oval ivory faceplate, slim adult proportions, articulated copper plates, graphite joints, amber chest line, five-fingered hands, and flat feet. Use Reference Video 1 only for the three-beat choreography, weight shifts, timing, and waist-height semicircular camera path; do not copy the masked performer, indigo suit, ribbon, or black-box theater. Use Reference Audio 1 only for the three action beats and room-to-step timing; replace cloth sound with restrained servo movement. Create one continuous four-second shot on a vast white salt flat at sunrise. The robot performs the same low arc, single pivot, and raised spiral gesture using empty hands, then settles facing the camera. Preserve the referenced robot identity and construction throughout. Synchronized audio: three ceramic-metal foot contacts, quiet servos, and open-air wind. No cuts, no humans, no ribbon, no theater, no dialogue, no music, no readable text, no logos, no brands, no products, no advertising, no watermark.",
