Hi @maintainers,

This PR is ready for review ✅.
However, merging is currently blocked because:

Vercel check is failing → Authorization required to deploy (likely a deployment permission/configuration issue).

Branch protection → Requires at least one approving review from a collaborator with write access.

The code changes themselves are passing the other checks.
Please review and approve when convenient 🙏.

Thanks!

Perfect!

Thanks for the feedback. I’ve removed all unrelated modifications from package.json (kept only "rate-limiter-flexible").
Also cleaned up backend/Routes/index.js — deleted commented code, kept only middleware-applied routes, and ensured a single export default router at the bottom.
