To isolate a UI component into a sandbox for visual iteration, you extract the existing component from the main app, rewrite its imports, and stub external dependencies to run it independently. This allows accurate redesigns against the original source code without hand-coding approximations.

Creating UI design variants from existing source code involves pulling the implemented component into a mockup sandbox. By isolating the original code and stubbing dependencies, you can generate multiple sandboxed representations to compare visual fidelity and iterate on different visual references.

Embedding an extracted component in an iframe mockup works by placing the isolated component into a specific sandbox artifact directory. The system rewrites imports and stubs external dependencies, allowing the component to render independently within an iframe displayed on the canvas for safe previewing.

You do not need to manually rewrite imports when extracting UI components for preview. The extraction workflow automatically rewrites imports and stubs external dependencies, enabling the component to run seamlessly within the sandbox environment without requiring the full application context.

You use a mockup sandbox instead of modifying main application code directly to ensure safe, isolated iteration. This approach uses real source code as the starting point while preventing unintended side effects, allowing you to freely redesign and create variants without breaking the main application.

Yes, you can extract multiple UI components to compare visual fidelity in a mockup. The workflow supports creating multiple sandboxed representations of isolated components, allowing you to iterate with variants and evaluate different visual references side-by-side on the canvas.
