Create a **PersistentVolumeClaim** named `app-data` that requests:\n - Storage: `1Gi`\n - Access mode: `ReadWriteOnce`\n - StorageClass: `local-path`\n2. Create a Pod named `data-pod` using `nginx:alpine` that mounts `app-data` at `/data`\n\n```bash\nkubectl get storageclass # verify local-path exists\n```",
