Oxblood Handrail Spiral Stairwell

An architectural photograph looking upward through a compact circular stairwell painted warm ivory, with a continuous oxblood-red steel handrail spiraling toward a small skylight. No people, no signs. Strong geometric composition with three visible flights and coherent steps, soft daylight gradient, plaster imperfections and matte painted steel. Editorial precision, restrained saturation, abstract beauty grounded in believable construction, no impossible stair intersections. Create exactly one finished image, aspect ratio 3:4. No collage or contact sheet. No watermark or signature. Keep all people original adults. Render at the native size available; do not add a frame.
