Trusted Types Enforcement

This scenario stubs window.trustedTypes so policy creation fails, matching browsers that enforce Trusted Types without allowing our hub-embed policy. The embed should abort safely, display the inline error UI, and avoid hydrating any blocks.

This harness is intentionally noisy:

Look for [hub-embed]:sdk TRUSTED_TYPES_ABORT errors — they confirm the guardrail is working.
Use the DevTools “Clear console” button before leaving so these expected errors do not follow you to other harnesses.

Mounting embed…Consent pending — telemetry buffers until consent is granted.
