从正上方看，珊瑚修复台上的一次固定

One original standalone documentary photograph directly overhead, landscape 3:2: a coral restoration worktable on a small research boat, with several healthy coral fragments in shallow trays, clean gloves, small calipers and a simple rope grid laid out around a central empty work area. Two adult conservation workers' hands enter from opposite edges to secure one fragment. Turquoise sea glimpsed past the table edge, noon sunlight, clear scientific procedure, credible marine biology materials. No labels, lettering, logo, watermark, dolls, glacier, collage or split panels.

一张从正上方拍摄的横幅纪实照片：小型研究船上，几盘健康珊瑚碎枝、干净手套、小卡尺和简单绳网围出中央操作区。两名成年保护工作者的手从两侧进入，正在固定一枝珊瑚。桌缘外可见青绿海水，正午光清晰，材料与动作符合真实修复过程，不写标签或图解。
