锐角三角的美术馆：19 度尖端与天窗网格

Design a museum on a trapezoidal site in the manner of I. M. Pei's East Building — the awkward plot resolved by splitting it into two triangles, producing a knife-edge corner of just 19 degrees that visitors instinctively reach out and touch. Compose sheer pink Tennessee marble walls meeting at an extremely acute vertical edge, joints only a few millimetres wide, no window or opening near the point, a broad paved plaza with small glass pyramid skylights in the ground, hard sunlight along the blade edge, low view up the acute corner, 24mm lens, architectural photography, ultra photorealistic, 8K
