楼梯井广场：层层下沉的方形水池

Design a sunken public court in the manner of Charles Correa based on a traditional stepwell: a square void cut into a plaza with broad stone steps descending on all four sides to a small pool at the bottom. Compose massive red sandstone blocks with crisp shadow lines at every tread, a plain rendered wall above painted a single deep colour, an astronomical diagram inlaid in the paving, no railings, hard Rajasthani sun making the steps read as a zigzag of light and dark, high oblique view into the well, 24mm lens, landscape architecture photography, ultra photorealistic, 8K
