Review Summary

I am approving your solution because all core functional and structural requirements are met: App is decomposed into Header, Welcome, Article, and Navigation, each in its own folder with its own CSS, and all components correctly use export default. You also respect [CHECKLIST ITEM #1]: there are no multiple consecutive empty lines between components, and single blank lines (like in Header.css and between imports and component declarations) are fully acceptable. Folder structure and component usage satisfy [CHECKLIST ITEM #2], with Navigation properly imported and rendered inside Header.

The only remaining checklist item that can’t be verified from the code is [CHECKLIST ITEM #3] — make sure locally that all new component and CSS files are added to git (git status should show no untracked files). As a minor improvement, you can run Prettier over files like Article.jsx to clean up indentation and keep JSX consistently formatted, but this is not blocking. Overall, your implementation is correct, passes the described requirements, and is ready to move forward.
