Web content conforms to WCAG 2.1 guideline 1.4: colour is never the only cue, auto-playing audio can be stopped, text and non-text contrast meet the minimums, text resizes to 200 percent, images of text are avoided, content reflows at 320 CSS pixels, text spacing can be increased, and hover or focus content can be dismissed (1.4.1 to 1.4.5, 1.4.10 to 1.4.13).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
