Advanced AI Prompt for Blue-Green Deployment on AWS with GitHub Actions

Act as a Senior DevOps Automation Engineer. Design a bulletproof GitHub Actions workflow YAML to execute a true Blue-Green deployment strategy targeting an AWS ECS Fargate cluster. The workflow must explicitly hand off the traffic shifting responsibilities to AWS CodeDeploy. Engineer the following sequential jobs: 1) Compile and push the Docker artifact to ECR. 2) Dynamically render a new ECS Task Definition. 3) Trigger the CodeDeploy `create-deployment` API using the `aws-actions/amazon-ecs-deploy-task-definition` action. 4) The CodeDeploy configuration must utilize the [LOAD_BALANCER_ARN] to route test traffic to the 'Green' target group. Implement an automated rollback trigger that instantly aborts the CodeDeploy shift and reverts to 'Blue' if the new [SERVICE_NAME] container within [ECS_CLUSTER_NAME] located in [AWS_REGION] returns 5xx HTTP codes during the bake period. Utilize strictly keyless OIDC for AWS authentication.
