光作为建材：光缝、中庭与反射照明

Design architecture where daylight becomes the primary building material. Shape spaces through light slots, courtyards, reflected illumination, and moving shadows inspired by Tadao Ando. Narrow slots cut at the junction of wall and ceiling washing light down the concrete, a small court bouncing indirect light deeper into the plan, no direct sun reaching the floor, the light source itself never visible, calm overcast daylight, eye-level composition, 35mm lens, ultra photorealistic, 8K
