深色高光表面水渍特写

超宽幅横向微距特写，深灰黑色高光片状表面占据大部分画面，表面分布多个圆形水渍、白色雾状污斑和右侧较大不规则水痕；表面底边平直，下方露出浅白色弧形边缘；冷调光线形成柔和反光，整体呈写实产品材质与污渍展示风格，画面比例约7:1，无人物出现。

Ultra-wide horizontal macro close-up of a dark charcoal-black glossy sheet-like surface occupying most of the frame, scattered with multiple circular water spots, white misty stains, and a larger irregular water mark on the right; the bottom edge is straight with a pale white curved rim visible below; cool-toned lighting creates soft reflections, realistic product material and stain showcase style, aspect ratio about 7:1, no people.
