Browser version, kernel, UA, Client Hints and runtime consistency check.

Chrome / Edge expose both the UA string and Sec-CH-UA fields; mismatches should be reviewed.

Blink, WebKit and Gecko affect Canvas, WebGL, plugins and API behavior, making the engine a core profile field.

If the server-observed User-Agent differs from the JS User-Agent, a proxy layer or script injection may be involved.
