Closes #300

[vercel]

@laurentketterle-hub is attempting to deploy a commit to the David Dada's projects Team on Vercel.

A member of the Team first needs to authorize it.

⚠️ Build Failure Analysis: The Vercel deployment is failing. Investigation reveals:

1. Node.js version mismatch: and require Node.js , but the file specifies (and Vercel defaults to whatever is configured).

2. Missing Next.js binary: is not being linked during install.

Suggested fix: Update to (or newer) and ensure Vercel uses the correct Node version. Also consider removing the stale (use only as the CI uses bun).

👋 Ping for review — this PR is >24h old. The Vercel check failure is an authorization issue (not code), requires Vercel re-auth from the repo owner. The code changes are ready for review. Thanks!
