rizalanggoro/arta — reverse-engineered prompt

Build me the Arta Android app from this repo. Please start by reading PRD.md and any agent notes, then make the mobile app and backend work together as a simple end to end product.

I want to be able to open the app, move through the main screens described in the PRD, enter and save data, and see it come back from the backend instead of just mock screens. Keep the UI clean and easy to understand, with sensible empty states, loading states, and error messages.

If something in the spec is missing, choose the simplest reasonable version and leave notes in the code. Make sure it runs locally, add any setup steps that are needed, and fix obvious build or lint issues. Look up current docs online if you need to.
