CSP Header Generator & Tracking-Linter
Update — 19.10.2026: Optional container optimization can remove an additional gtag.js load. It does not prove that measurement connections or their CSP permissions are unnecessary. This preset covers the displayed provider selection, not every destination, gateway, preview connection or custom tag. The actual script, image, frame and connection requests determine the required policy; a missing separate gtag.js request alone is not a tagging error.
