WCAG 2.x contrast report for palettes.css (generated by gen_palettes.py)
Thresholds: text pairs 4.5:1 or better; UI pairs (focus ring, strong rule) 3:1 or better.
From 1.7.0 each site and scheme also lists the matrix tints (row tint, row hover, heat 0 to 4) and the column-group accents.
Every pair below was computed from the emitted hex values with the WCAG relative-luminance formula.
