  "prompt": "Opaque solid satin silver jewelry sheet with fine reticulation: chaotic angular corrugations, shallow connected ridges and tiny concave wrinkles, resembling a delicate folded terrain, no hammered circular dimples, no punched holes, no grit. Even cool silver-gray metal base color with extremely restrained natural contrast. 12 cm square, fine irregular structure. Photorealistic square diffuse/albedo texture asset for a PBR material library, perpendicular orthographic view of a continuous flat surface, full bleed, no object, scene, border, scale ruler, text or watermark. Neutral uniformly diffuse cross-polarized illumination, no cast shadows, AO, directional shading, vignette, strong glints or reflections. Preserve intrinsic detail at consistent scale. Edges intended to tile, avoid a single dominant mark and broad lightness gradients. 1024 square or higher. This is a visual material study.",

Normal: periodic multi-scale Gaussian bands, robust contrast normalization, material-specific cavity/joint masks and central-difference tangent-space gradients.
