Review Summary

Your solution is approved because it meets the core requirements of the task and does not contain any critical blocking issues. App.jsx is cleanly decomposed into Welcome, Header, and Article, and the navigation has been correctly moved into its own Navigation component that Header imports and uses. Each component (Welcome, Header, Article, Navigation) lives in its own folder under src/components with a corresponding CSS file, satisfying the structure and [CHECKLIST ITEM #2] “separate folder per component” requirement. The JSX is concise and avoids the “bad example” of multiple empty lines between components, so [CHECKLIST ITEM #1] is also satisfied. All components use export default, and there are no obvious runtime or import errors in the code you’ve shown.

The only remaining points are non-code items that I can’t verify here: make sure all new/changed files are committed to git ([CHECKLIST ITEM #3]), that you’ve run npm test, and that your PR includes the correct demo link as required by the task. Overall, this is a solid, well-structured decomposition—nice work keeping the components and styles clearly separated.
