/*
  Palette provenance. This file is the only place colour literals may live.
  Source: brand/LOGO HOLKERCOIN PNG.png (IHDR 2000x2000, 8-bit, colourtype 6 RGBA, fully opaque).
  Method: k-means (k=4, farthest-point init, 25 iterations) over a 60k-pixel subsample; each centroid
  was then snapped to the nearest real pixel in the full image. Coordinates are x,y from top-left.
    bg      #000906  share 92.8%  pixel (0,0)
    accent  #02f2ad  share  7.1%  pixel (1254,718)
    mid     #0d926c  share  0.1%  pixel (498,1159)
    deep    #084e3b  share  0.1%  pixel (691,1080)
  scripts/gates.mjs re-reads each coordinate from the PNG and fails if the token differs.
  The transparent export (brand/LOGO HOLKERCOIN PNG...png) holds the same accent: #01f3ad at (1261,718).
  A stray pure-green cluster in that file is an edge-antialias artefact and is deliberately not used.
