  "prompt": "Generate a square orthographic 1024+ PBR diffuse/albedo of a flat sealed copper-mesh phenolic laminate. Extremely fine woven copper-colored hair wires, smaller than 1 mm, visible as closely spaced woven dots and short threads under a dark amber continuous resin surface. Fine, slightly irregular pitches create rich micrograin, with no visually dominating square grid at thumbnail scale. Use one neutral diffuse exposure, perfectly equal average color and brightness in every quadrant and at all four edges, no banding or gradients. Arrange the detail so offset repeat does not reveal rows or seams. Full bleed, no perspective, transparency, shadows, text, physical object, frame or baked reflections.",

  "method": "Albedo: periodic-plus-smooth decomposition via FFT Poisson solve to reduce edge mismatch. Normal: periodic multi-scale Gaussian bands, robust contrast normalization, material-specific cavity/joint masks and central-difference tangent-space gradients. Roughness: material preset plus local detail and joint variation. All data channels are estimates, not measured surface response.",
