Photorealistic full-frame background of a rough distressed grunge surface, like aged charcoal-gray plaster over coarse woven canvas, with layered scuffs, cloudy stains, faded scrape marks, tiny scratches, worn patches, and subtle dust speckling. Keep the composition flat, square, and edge-to-edge with no central subject, darker smoky corners and a softly mottled lighter gray center for usable copy space. Lighting is diffuse and low-contrast, as if photographed in an overcast studio with gentle side falloff, creating a moody industrial feel. Color palette of deep graphite, ash gray, muted silver, and dirty white. Shot as a high-resolution macro texture on a 50mm lens, f/8, crisp detail across the plane, natural grain, matte finish.
