about

nx_uiq_color.nx -- SOVEREIGN UI-QUALITY color engine (no main). The ONE WCAG 2.x relative-luminance + contrast-ratio implementation for the whole nx_uiq_* family, PLUS a CSS color parser (#rgb/#rrggbb/rgb()/named) and a custom-property color-token scanner, so the family computes contrast on the REAL colors extracted from a page instead of one hardcoded token pair. The math is reused verbatim from nx_contrast (KAT'd to the WCAG reference black/white=21.00, #767676/white=4.54). CONSOLIDATION SEED: nx_contrast + nx_ui_contrast + nx_brand_guard migrate onto this on next touch (D001 migrate-on-touch), collapsing 3 duplicate luminance kernels -> 1. license_tier: ORIGINAL genealogy: w3.org/TR/WCAG21 relative-luminance + contrast-ratio (verbatim)
