New in V4.1.1: a web page may not prevent the browser's modes that render pages to the user's preferences, nor explicitly override the user's choices for documented platform accessibility features within those modes, unless essential to the page's information or function; for web pages the platform is the user agent. It limits CSS such as forced-color-adjust to essential cases; examples of such features are text size, contrast, colour filters, text cursor and pointer size.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
