Web content conforms to WCAG 2.1 guideline 2.5: path-based or multipoint gestures have single-pointer alternatives, actions fire on release and can be abandoned, the visible label is part of the accessible name, and motion-triggered functions have a control alternative and can be disabled (2.5.1 to 2.5.4).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
