Where ICT offers visual modes, it must provide features that let people make better use of limited vision. Notes name magnification, a smaller required field of view, control of contrast, brightness and intensity, alternatives to depth cues, and as best practice a smallest text x-height of 8 CSSpx (about 1.2 mm at 400 mm); C.4.2.2 uses the LV column of Annex B or direct evidence.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
