frappe/mobile ? reverse-engineered prompt

Build me a mobile app for Frappe and ERPNext that lets users access their desk from a phone.

I want it to feel like a real companion app, with a login flow, a home screen for browsing the desk, and the ability to open records, create and update docs, add or remove assignees and tags, manage attachments, leave comments, send email, and see the timeline on each document. It should also have the quick search or awesome bar so users can find things fast.

Make it simple and clean, and keep the app working on both Android and iPhone. Use the existing Flutter setup in this repo, follow the current app style, and wire up the state and data handling in a sensible way so the screens stay organized. If you need to, look up current docs online for Flutter or Frappe behavior.
