The deployable Next.js demo behind the new Daytona cookbook recipe. A minimal CopilotKit Built-in Agent whose only added capability is the recipe's runCode server tool — executes Python / TypeScript / JavaScript in an isolated Daytona sandbox and streams the result back to the chat via a custom useRenderTool card (fixed-height streaming code pane with react-syntax-highlighter + vscDarkPlus, mirroring @copilotkit/react-ui's own CodeBlock, and a fixed- height result pane with a 'Generated code:' / 'Result:' label pair). The agent's system prompt instructs it not to restate stdout in chat text since the renderer already shows it. Standalone npm project — intentionally not in the monorepo's pnpm workspace (matches the existing examples/showcases/* convention; only generative-ui- playground is in the workspace globs). Validated end to end against published @copilotkit/runtime@1.58.0 with both Python and JavaScript snippets round- tripping through real Daytona sandboxes. OSS-222
