绿玻璃斜切塔：两片镜面在角落相接

Design a mixed-use tower in the manner of Kevin Roche's One United Nations Plaza — a flush blue-green mirror-glass skin with no visible frame anywhere, the mass sliced by sharp 45-degree setbacks so the building reads as a single folded crystal rather than as stacked floors. Compose an uninterrupted reflective envelope where window and spandrel are indistinguishable, angled cuts at the top and at one corner, the city and sky doubled in the surface, no cornice or crown, clear cold daylight, low upward three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
