Square 1:1 frame, full-bleed opaque top-down photograph of pale beach sand, finish continuous to every edge. One thin curved tide line of fine shells and chalk fragments gathers across the bottom fifth with modest natural unevenness. A single piece of soft blue-green sea glass rests just above the arc on otherwise untouched sand, catching one small bright highlight. The top seventy percent of the frame stays clear and empty. Diffuse beach morning light, fine grain with small pits, no styling. No text, no footprints, no people.
