Split-frame product comparison photo, one vertical seam dividing the square image. Left half: a black EPDM rubber tarp strap coiled on weathered wood in bright summer sunlight, surface intact, deep matte black, supple. Right half: a generic cracked and faded grey elastic cord on the same wood, dried out, surface crazing and fraying visible. Same camera position and height both sides so the comparison reads instantly. Natural daylight 5500K. Leave a clean band across the top for a headline to be added later. No text, no logos, no watermarks, no badges, no people's faces. Aspect 1:1, 2000x2000.
