Greptile Summary

This PR fixes broken navigation links in the pages/challenges.html file that were causing 404 errors. The changes address two specific navigation issues:

1. Challenges navigation link: Updated from an absolute path /challenges to a relative path challenges.html on line 27
2. Footer Home link: Changed from / to ../index.html#top on line 208

These modifications align the navigation patterns with the rest of the codebase's static file structure. The CodeClip application is a static site hosted on GitHub Pages (as evidenced by the deployment workflow), which requires relative file paths rather than server-side routing paths. The footer Home link correction properly navigates from the /pages subdirectory back to the root index.html file and includes the #top anchor for proper page positioning. This ensures consistent navigation behavior across the application's file structure and resolves the 404 navigation issues users were experiencing.

Confidence score: 4/5

• This PR is safe to merge with minimal risk as it only fixes broken navigation links
• Score reflects straightforward link corrections that align with existing codebase patterns
• No files require special attention as the changes are simple href attribute updates
