- utils/accentColor (8): hexToRgb parsing, lighten/darken channel math, rgba clamping, WCAG relativeLuminance (black=0/white=1), contrastingText threshold, varNameFromToken, and derivePrimaryPalette's full 10-token output. - utils/matrix-uia (7): UIA flow helpers — getSupportedUIAFlows, completed/params/session/errcode/error accessors, getUIAFlowForStages (incl. the single-extra-dummy rule), has/requiredStageInFlows, and getLoginTermUrl language fallback. Full suite now 123 tests, all passing. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
