stemlen/Fairlx ? reverse-engineered prompt

Build me an enterprise project management app for teams that feels modern and easy to use, but can still handle bigger companies.

I want people to be able to sign up with a personal account or join an organization, then create workspaces, spaces, projects, and tasks. It should support things like Scrum and Kanban boards, custom task statuses, subtasks, labels, assignees, comments, time tracking, and saved views. Make it so managers can set permissions for different roles, and admins can control who can see or change things.

Add AI helpers that can suggest workflows, help with task setup, and generate useful documentation. I also want usage based billing for organizations, with clear limits, invoices, and account suspension if needed. If possible, connect it to GitHub so projects can link to repositories and keep things in sync.

Please make it production ready, polished, and organized for real teams. Use current docs online if you need to.
