makerkit/nextjs-saas-starter-kit-lite — reverse-engineered prompt

I want a lightweight SaaS starter app built from this repo that I can use as the base for a real product. Please keep it clean, modern, and responsive, with a simple public marketing site, user sign up and sign in, protected app pages after login, and a basic profile and settings area people can actually use. Use Supabase for authentication and the basic database pieces that are already expected here.

Please wire up the app so it runs locally, make the main branding and site text easy to change through environment settings, and keep the code organized and TypeScript strict. I also want the basic translation support working for both public and logged in pages, plus sensible route protection so unauthenticated users get redirected correctly.

Don’t add extra big features like billing, teams, blogging, or admin stuff. This should stay as a solid lite starter. If anything in the docs is outdated or missing, look up the current docs online and use the best supported setup.
