Build pipelines
Run smoke tests against the deployed URL after each git push; App Platform injects different hostnames per branch.

Observability
Stream logs to Spaces or external SIEM; redact Authorization when sharing CORS failure traces.
Alert when OPTIONS latency spikes after scaling workers horizontally.
