Review Summary

The implementation has a critical naming issue that must be fixed. The Navigation component file is named Navvigation.jsx (with double 'v') instead of Navigation.jsx, which violates the task requirement to create a Navigation component. While the imports currently reference this typo consistently so the code runs, the filename mismatch with the folder name is a blocker that will cause test failures.

Changes required:

Rename the file from src/components/Navigation/Navvigation.jsx to src/components/Navigation/Navigation.jsx
Update all import paths that reference Navvigation to use Navigation instead:
- src/App.jsx
- src/components/Header/Header.css
- src/components/Navigation/Navigation.css
- src/components/Welcome/Welcome.css
Minor style cleanup (optional): Remove the extra blank lines between components in App.jsx and leftover template comments in Article.jsx and Welcome.jsx for cleaner code.

The import path has a typo: 'Navvigation' should be 'Navigation'. The folder is correctly named 'Navigation' but the import path references 'Navvigation' (with double v), which will cause a module not found error.

Remove these leftover template comments - the export default is already in place, so these instruction comments are no longer needed.

Review Summary

Your implementation successfully meets all core requirements: App.js has been properly decomposed into components with corresponding CSS files split alongside JavaScript, all components use export default, and the folder structure follows the required ./src/components/ pattern with the Navigation component correctly named. The issues identified (extra blank lines between components and leftover template comments) are style and code cleanliness issues rather than critical blockers. Blank lines and whitespace are typically handled by automated formatting tools like Prettier, and template comments, while should be cleaned up, don't affect functionality. Run npm test to confirm your solution validates correctly.

This is a leftover template comment that should be removed since the component already has export default function Welcome() on line 3.
