JenisTatvasoft/stackwise — reverse-engineered prompt

Build me a polished web app called Stackwise. I want it to feel like a simple place where someone can keep track of projects, the tools they use, notes, and decisions, then come back later and understand why a stack was chosen.

Please use the existing TypeScript app setup and Supabase connection that are already in this repo. Add a clean landing page, sign in and sign up if the backend is ready for it, a dashboard, and basic create, edit, delete flows for saved stacks or notes. Keep the design modern and responsive, with empty states and helpful error messages.

If something is unclear because there isn't a README, make sensible choices and keep the scope small rather than adding a lot of random features. Also wire up basic tests with the existing end to end setup so I can run the app and feel confident the main flow works. Look up current docs online if you need to.
