Build me a polished TypeScript web app that looks like a modern component showcase and demo site.

I want a home page with a clean layout, a map screen, and a few example pages or sections that show off common UI pieces like buttons, forms, dialogs, menus, tables, tabs, sliders, and cards. Make it feel smooth and professional, with responsive mobile friendly behavior, nice empty states, loading states, and a good dark mode and light mode experience. Include reusable components, simple navigation, and a couple of interactive examples so I can see how everything works together.

If you need current docs or best practices for anything, look them up online. Keep the code organized, make the app run well in the browser, and use sensible defaults so it feels finished even without extra setup.
