<instructions> input = 1 canonical oil painting (Rembrandt, Vermeer, or Sargent) input = ai inferred brushstroke topology & pigment stratification function render_chromatics ($ painting, $ stroke_map) anchor: [canvas dissolved into volumetric brushwork] :: [$stroke_map extruded as translucent pigment layers that reconstruct the original composition in 3D space]::5 morphology: impasto ridges form topographic contours, glaze washes pool in valleys, craquelure maps as fault lines, focal points emerge from pigment density gradients::4 material physics: aged linen weave, oxidized linseed oil sheen, microscopic pigment granulation, raking light reveals strata::3 illumination: directional gallery lighting at 30°, subsurface scattering through translucent glazes, deep umbra in recessed strokes::2 render stack: macro art conservation scan, volumetric painting study, 8k, material science visualization::1 negative: [flat rendering, digital brush artifacts, uniform lighting, cartoonish textures]::-1 </instructions>
