Surface texture (fabric weave, paper grain, painted finish) still visible underneath. No painted-on flat patches. The damage must be CLEARLY VISIBLE at a glance, but rendered with PHOTOGRAPHIC REALISM — muted realistic colours appropriate to this specific damage type, no vivid or oversaturated tones, no spotlight, no halo, no extra dramatic shadow. Compose the damage asymmetrically in the photo frame, never perfectly centred. Soft feathered edges that blend into the underlying material's texture (fabric weave, glass curvature, paint surface visible through the damage, NOT painted-on or decal-like). Single occurrence at real-world scale; lighting matches the rest of the photo. No text, no logos, no watermarks, no people, no gore, no biohazard imagery, no swarms, no cartoonish exaggeration.
