What you'll build

You extend the beginner static S3 + CloudFront site into a dynamic one. You add a Lambda function that returns JSON, expose it through an API Gateway HTTP API, and change index.html to fetch the API and render the list in the browser. You also learn to invalidate the CloudFront cache after redeploying. All identifiers in this tier are placeholders — never paste a real account ID or ARN.
