It supports three patch strategies: `merge`, `json`, and `strategic`.\n\n**Your task:**\n\nA Deployment named `patchme` is running in the `default` namespace with 1 replica.\n\n1. Use `kubectl patch` to update its replica count to **3**\n2. Use `kubectl patch` to add a label `env=staging` to the Deployment's **pod template** (`.spec.template.metadata.labels`)\n\n```bash\n# Verify:\nkubectl get deploy patchme -o jsonpath='{.spec.replicas}'\nkubectl get deploy patchme -o jsonpath='{.spec.template.metadata.labels}'  \n```",
