# letbe-ds — measured contrast (generated by scripts/audit-contrast.js)

Every meaningful token pairing in the shipped theme, measured per WCAG 2.x
(4.5:1 normal text, 3:1 non-text UI). Disabled pairs are listed and marked
exempt (WCAG 1.4.3 exception); advisory rows have no normative requirement
but are tracked so drift stays visible. Regenerate after any token change.
