Build me an open source habit tracking app that feels like a modern PWA and works well on mobile and desktop.

I want users to sign in, create habits in plain language, mark them done, and keep streaks going. It should support proof based check ins with photo or video uploads, smart reminders, and real time syncing across devices. I also want an AI coach chat where people can ask for help, get suggestions, and have habit completions checked by AI. Make it work offline too, so users can log habits even without internet and sync later.

Use a frontend, a backend API, and Supabase for auth, database, and realtime updates. Keep the UI clean and friendly, with screens for the main dashboard, individual habits, chat, and camera or proof capture. If you need to look up current docs online, go ahead.
