曲面楼梯与扶手细部：手工感的金属与木

Design a public stair in the manner of Togo Murano where the balustrade curves in one continuous sweep from ground to landing, its handrail a single piece of dark polished wood shaped to the hand and its supports slender hand-forged brass. Compose the helix of the rail spiralling upward, the underside of the flight rendered as a smooth plaster soffit with no visible structure, a terrazzo floor, a shaded hall beyond, warm low light glinting on the brass, low view up the spiral, 24mm lens, interior photography, ultra photorealistic, 8K
