To extract a UI component into a mockup sandbox, the skill analyzes the component's dependencies, rewrites its imports, and stubs external calls to preserve visual fidelity for isolated design iteration.

Yes, you can preview an extracted UI component in isolation by embedding the result in an iframe preview within the mockup sandbox, allowing you to iterate on the design without rebuilding from scratch.

Creating design variants from an existing navbar involves pulling the component into a standalone mockup sandbox, using the extraction workflow to stub external calls, and generating visual variants on the canvas for comparison.

Visual fidelity is lost when dependencies are not properly resolved, but this skill preserves the original appearance by analyzing dependencies, rewriting imports, and stubbing external calls during the component extraction process.

Yes, this frontend redesign workflow supports isolated iteration by pulling the target component into a standalone mockup sandbox, ensuring that external calls are stubbed so the main app remains unaffected during design exploration.

You need to stub external calls during component extraction when moving a UI component into a mockup sandbox, ensuring that the isolated design environment preserves visual fidelity without requiring the main app's full runtime.
