Gemini controlled-edit prompt
Use the uploaded empty-room photo as the controlling reference. Edit that image; do not create a different room. Stage it as a restrained [STYLE] [ROOM TYPE] for [LIKELY OCCUPANT]. Add only movable furniture and decor. Lock: camera, crop, perspective, walls, openings, ceiling, floor, built-ins, fixtures, exterior view, lighting direction, material colors, and visible condition. Furniture must be correctly scaled, physically grounded, and arranged with realistic circulation. Match shadows and reflections to the source. No renovation, repairs, architectural changes, hidden defects, text, people, pets, or logos. Return one photorealistic image at the source aspect ratio.
