装饰艺术楼梯：弧形扶手与几何栏杆

Design a Staircase in the Art Deco style, sweeping in a generous curve with a polished brass handrail following the arc. Compose the balustrade from fan and sunburst panels in brass and black lacquer, lay marble treads with an inlaid geometric border, and run a stepped skirting profile. Hang a tiered geometric pendant down the stairwell and mount matched wall sconces at each landing. Keep the palette to black, cream, marble and polished brass. Light it warmly and dramatically so the brass throws strong reflections. Opulent but disciplined, low eye-level view, 28mm lens, interior photography, ultra photorealistic
