StarchBond™ Structural Unit close-up (the brick that looks suspiciously snackable)

    "prompt": " Studio photo of a single rectangular brick on a neutral gray background, lit like a product shoot. The brick surface should read as compacted regolith: matte, dusty, reddish-brown with tiny specks, but with a faintly baked/porous texture hinting at starch. Include a subtle stamped mark on one face reading “StarchBond™” and a small scale reference (a ruler or gloved hand) to show it’s brick-sized. A few crumbs/dust grains around it to suggest brittleness without making it look like a cookie."
