drun16/flask_rbac_project ? reverse-engineered prompt

Build me a Flask web app for user sign up, login, and logout, with proper password hashing and role based access control.

I want two roles, User and Admin, where normal users only see protected pages they are allowed to access, and admins get a full admin dashboard where they can manage users and roles. Please include a clean setup for the database, migrations, and a simple way to seed the first admin account and roles. It should be ready to run locally with SQLite, but also be easy to deploy with a production database setup.

Make the app feel like a real starter project, not just a demo, so include the basic structure for authentication, admin pages, and a few tests with pytest to confirm the login and permission logic works. If you need to check current docs for any Flask extensions, feel free to look them up online.
