斜张巨构：塔柱、缆索与桥面合为一体

Design a cable-stayed bridge where pylons, cables, and deck form one integrated structural system. Emphasize engineering clarity, long-span performance, and visual lightness inspired by Norman Foster. Slender tapering pylons rising far above the deck with cables fanning symmetrically, the deck reading as a thin line, every element sized exactly to its load, mist filling the valley below, dawn light behind the pylons, wide establishing view, 85mm lens, ultra photorealistic, 8K
