  "notes": "Compact manifest. The harmony library regenerates visible harmonies from the deterministic seed + index instead of downloading an expanded JSON array. 8,192 harmonies are produced by cycling 23 canonical color-theory schemes against deterministic base hues. Stream definition matches @auric-artisan/palette-gen's xorshift32 PRNG so the two datasets share a deterministic substrate."
