进化之桥电影镜头提示

一个蜿蜒的单拱桥，在镜头中延伸至远方。桥的建筑风格沿其长度无缝过渡：始于罗马石桥，渐变为中世纪吊桥，再是维多利亚时代的铁桁架桥，最终演变成未来主义的复合材料结构。每个桥段都有符合其时代特征的旅行者和风化痕迹。山谷下方弥漫着晨雾，柔和的光线穿透云层。8K。

**Original English:**
A cinematic shot of a single, winding bridge stretching into the distance. The architecture transitions seamlessly along its length: starting as Roman stone, becoming a medieval drawbridge, then a Victorian iron truss, and finally a futuristic composite material. Each section has era-appropriate travelers and weathering. Morning mist fills the valley below, with soft light breaking through clouds. 8K.
