          ```

          ### Manual Configuration
          ```bash
          # Use generated TOML or YAML
          cp vapora-solo.toml /etc/vapora/config.toml

          kubectl create configmap vapora-config --from-file=vapora-solo.yaml
          ```

          ## Validation

          All artifacts have been:
          - Generated from validated Nickel configurations
          - Validated for syntax and structure
          - Tested with Kubernetes dry-run
          - Generated with consistent templates
