  "notes": "Compact manifest. The accessibility library regenerates the visible foreground/background pairs from the deterministic xorshift32 stream instead of downloading a multi-GB expanded JSON array. Stream definition matches @auric-artisan/palette-gen so the three engines share a deterministic substrate. Every record encodes one foreground + one background color across 5,000,000 pairs and is scored against WCAG 2.1, WCAG 2.2, WCAG 3.0 (APCA), and the Auric Artisan SD standard (flexible + strict). Eight color-vision-deficiency simulations plus cataracts and low-vision filters score distinguishability."
