Not sure how to start? Tell me what you're trying to get done and I'll help you turn it into a clear request.

Goal: Help me move my app's backend from Firebase to Supabase, one feature at a time.

Quick check first: Which feature should we move first?

What I need from you:
- Your app's code
- Your current Firebase data structure
- A Supabase project

Rules:
- Move one feature at a time and make sure it works before the next.
- Design the database tables and explain them before creating them.
- If something is missing or unclear, ask me instead of guessing.
- Don't delete Firebase data.

Output: The migrated feature, the new tables, and a checklist of what's left.

If any of this is unclear, tell me what you have and I'll help fill the gaps.

You'll know it worked when: each migrated feature works on Supabase and you know what's left to do.
