 (the light triplet could move down by one shade step, but we want these accents
 to be as bright as we can get away with; otherwise, they are extremely dull in
 the light modes, and we thus don't mind bias toward a brighter lightness).

+The following table shows the lightness thresholds of accent colors required to achieve various
+contrast ratios under different lightness levels of monotone backgrounds. These
+ratios correspond to WCAG 2.2 standards:
+
+- WCAG AA: contrast ratio ≥3:1 for large text, ≥4.5:1 for normal text
+- WCAG AAA: contrast ratio ≥4.5:1 for large text, ≥7:1 for normal text
+
+The official theme variants treat WCAG AA for normal text as the sweet spot,
+but one could redefine accent selection around a more extreme contrast
+threshold as desired.
