Reconstruct a geometric PNG (logo, icon, monogram) as a clean native SVG with exact geometry and gradients, using an analyse -> measure -> model -> check -> residuals iteration loop scored by perceptual metrics. Use when asked to vectorise, trace or convert a PNG/WebP logo to SVG, recreate a logo's geometry, rebuild a logo as editable vector, or produce colour variants of a reconstructed logo. Not for photos, textures, or organic artwork.
