Fix React Firebase Upload Error

My React + Vite app (hosted on Vercel and backed by Firebase) is failing when users try to upload images—the issue shows up in the middle of the upload process, never completing or returning a URL. I need someone to jump in, pinpoint the cause, and get image uploads working smoothly again.

The codebase is clean, TypeScript-friendly, and split into distinct components. You’ll have access to the Firebase project (Storage and Auth), the repo on GitHub, and a staging deployment on Vercel so you can reproduce the bug quickly.

What I need from you:
• Diagnose the exact failure point in the current upload logic (React hooks + Firebase Storage SDK).
• Implement a robust fix that handles all standard image formats and respects current storage rules.
• Push a tested solution via PR, including any necessary updates to Storage rules, environment variables, or Vercel settings.
• Verify the fix on staging; once confirmed, I’ll handle production deployment.

If you’re comfortable debugging React/Vite apps that talk to Firebase Storage and you can turn this around swiftly, let’s talk.
