/*
  Single home for colour literals (standing rule 4).

  PALETTE PROVENANCE (sampled, not invented)
  Method: k-means on opaque pixels (deterministic farthest-point seeding, 14 iterations,
  every 3rd pixel), then each centroid is snapped to the nearest REAL pixel; its source
  file and (x,y) are given beside each token. Stride-3 grid, origin top-left.
    brand = brand/LOGO SECUTY PNG.png      (2000x2000, RGBA, alpha always 255; k=6)
    s1    = reference/SECUTY 1.jpg.jpeg    (1600x900 JPEG slide; k=12)
  The transparent logo (brand/LOGO SECUTY PNG...png, 94% alpha 0 stored as rgb(0,0,0))
  was only used for the ink check and for premultiplied resizes in brand/make-assets.mjs.
  Values with 8 hex digits are a sampled colour plus an alpha, marked "derived".
