/*
  Palette provenance. Method: k-means (k=12, seed 2, 8-bit RGB, every 40th pixel) over
  brand/LOGO ROOK PNG.png (2000x2000, IHDR colortype 6, alpha 254..255, so effectively
  opaque), each centroid then snapped to the nearest real pixel; that pixel's coordinate is
  recorded. The mint token comes from a saturation search over reference/SAMPUL ROOK JPG.jpg.jpeg
  (the only green in the supplied art), also snapped to a real pixel.
  The gate re-reads each pixel and fails on any mismatch.
