what is WebGL fingerprint countermeasures?

Per-technique countermeasures on the webgl surface: how the spoof works, which tools implement it, which detector or coherence-check catches it, and the residual tell that survives a correct application. Organized surface -> technique -> counter-detector.. Distilled from an internal techniques catalog. Teaching framing, not a how-to. Signals drift; asOf 2026-06-15. implementedBy = tool slugs; caughtBy = detector / coherence-check / KB-key names.
