kanbn/kan — reverse-engineered prompt

Build me an open source Trello style project management app called Kan.

I want people to create workspaces, invite team members, and manage projects with boards, lists, and cards. Users should be able to control who can view or edit boards, add labels, filter cards, leave comments, and see an activity history for card changes. Include reusable board templates and a simple way to import boards from Trello.

Make it feel clean and modern, with a polished dark mode like a serious productivity tool. It should support login, email setup, a PostgreSQL database, and be easy to self host with Docker Compose. Use the stack that makes sense for this kind of TypeScript web app, and look up current docs online if you need to.
