贝壳潮线上方的一粒海玻璃

No text, no footprints, no people. A top-down photograph on a square 1:1 frame, full-bleed and opaque, of pale beach sand continuing to every edge in diffuse morning light, with fine grain and small pits, and no styling. Along the bottom fifth runs one thin curved tide line of fine shells and chalk fragments, with modest natural unevenness. Just above that arc, on otherwise untouched sand, rests a single piece of soft blue-green sea glass catching one small bright highlight. The upper seventy percent of the frame is left clear and empty.

不要文字，不要脚印，不要人。1:1 方形画幅的俯拍照片，满幅不透明，浅色海滩沙地延伸到每一条边，清晨漫射光，带细腻颗粒和细小的凹坑，不做任何造型。画面底部五分之一处横着一条细细弯曲的潮线，由细碎的贝壳和白垩碎片组成，带着适度的自然不均匀。紧贴弧线上方、原本平整未被扰动的沙面上，躺着一粒柔和蓝绿色的海玻璃，捕捉到一个小小的明亮高光。画面上部七成保持干净空白。
