貝殼潮線上方的一粒海玻璃

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，不要腳印，不要人。1:1 方形畫幅的俯拍照片，滿幅不透明，淺色海灘沙地延伸到每一條邊，清晨漫射光，帶細膩顆粒和細小的凹坑，不做任何造型。畫面底部五分之一處橫著一條細細彎曲的潮線，由細碎的貝殼和白堊碎片組成，帶著適度的自然不均勻。緊貼弧線上方、原本平整未被擾動的沙面上，躺著一粒柔和藍綠色的海玻璃，捕捉到一個小小的明亮高光。畫面上部七成保持乾淨空白。
