Review Summary

I am approving your solution because all core requirements appear to be met: App.jsx is correctly decomposed into Header, Welcome, and Article components, each component lives in its own folder with its own CSS file, and all components use export default as required by the tests. The overall structure under src/components follows the expected pattern, and the optional Navigation component is reasonably kept inside Header, which is allowed by the task. There is no evidence of broken functionality or missing mandatory features based on the code that was reviewed.

The main thing to keep in mind going forward is to keep JSX formatting tidy: you have a few extra blank lines inside Article.jsx between JSX blocks, which is not a blocker but could be tightened for readability and to stay close to [CHECKLIST ITEM #1]. Also make sure locally that all new component and CSS files are added to git and that npm test passes before final submission, since those process steps can’t be checked from the code alone. Overall, this is a solid, well-structured decomposition of the original App and is good progress for this task.
