**Bug Description**

In the Temporal Policies section (07-Centralise and govern your AI infrastructure), the workshop says "Then open http://localhost:5173." But the app gets deployed on a remote VM accessed through CloudFront, so this instruction is invalid.

**Sub-issue: Vite host check blocks CloudFront hostname**

Symptom: "Blocked request. This host (dogu4gm1cbm4c.cloudfront.net) is not allowed."

Cause: Vite's dev server rejects requests from hostnames not in its allowlist.

**Suggested Fix**
Add `allowedHosts: true` to `vite.config.ts`.
