Habil-0105/ayam-in ? reverse-engineered prompt

Build me a simple modern web app where people can sign in, save their data, and view it in a clean dashboard.

I want it to feel polished and easy to use on desktop and mobile, with a nice landing page, a basic account flow, and a place where logged in users can manage their info. Use Supabase for the backend and database, and make sure the app is ready to deploy cleanly.

Please wire up the main pages, handle loading and error states, and make it look good with a straightforward UI. If you need current setup details, look up the latest docs online and use the existing project structure.
