Write a Kubernetes deployment manifest

Write a production-ready Kubernetes Deployment and Service manifest for [App Name]. Set explicit CPU and memory requests and limits on the container. Configure both a liveness probe and a readiness probe with appropriate paths, initial delays, and failure thresholds. Use a RollingUpdate deployment strategy with sensible maxUnavailable and maxSurge values. Mount a ConfigMap to inject environment variables and add pod anti-affinity rules to prevent multiple replicas from landing on the same node.
