Amplify Astro CI/CD
Ship a static Astro site to Amplify Hosting with staging, PR previews, GitHub CI gates, and teardown.
Connect a minimal Astro sample to Amplify Hosting with GitHub: long-lived staging and main, PR previews on staging only, Actions as the merge gate, and ruleset delete protection so auto-delete head branches cannot remove staging on promote.
Covers creating the repo and app in the Console, amplify.yml, hygiene workflows, prove-the-flow (feature → staging → main), and tearing down the Amplify app when the lab is done.
