Advanced AI Prompt for Kubernetes Kustomize Overlays for Multi-Env

Act as a GitOps Configuration Manager. Generate a complete Kustomize overlay structure specifically tailored for the '[ENV_NAME]' environment (e.g., production vs. staging). The overlay must cleanly mutate a generic base deployment without altering the original files. Instruct Kustomize to patch the replica count to '[REPLICA_COUNT]'. Implement a strategic merge patch or JSON patch to aggressively override the container resource limits, setting the CPU limit to '[CPU_LIMIT]'. Furthermore, implement a `ConfigMapGenerator` that dynamically constructs an `application-config` ConfigMap injecting the environment variable `LOG_LEVEL` set to '[LOG_LEVEL]'. Output the perfectly structured `kustomization.yaml` linking these assets.
