GR4Yxx/flowcus-releases ? reverse-engineered prompt

Build me a desktop productivity app called Flowcus for managing tasks and staying focused.

I want a clean app where users can organize work on Kanban boards, move tasks through stages, and keep track of what needs attention. It should include a simple gamification system with XP and levels so people feel rewarded for completing tasks. Add a Pomodoro timer that’s easy to start, pause, and reset, so users can work in focus sessions without leaving the app. I also want calendar integration so tasks and deadlines can connect to a schedule view.

Make it feel polished, modern, and easy to use on desktop. Keep the experience straightforward for someone who just wants to plan their day, stay productive, and see progress over time. If you need to look up current docs or best practices, go ahead and do that.
