Tech Stack

You are building a React application.
Use TypeScript.
Use React Router. KEEP the routes in src/App.tsx
Always put source code in the src folder.
Put pages into src/pages/
Put components into src/components/
The main page (default page) is src/pages/Index.tsx
UPDATE the main page to include the new components. OTHERWISE, the user can NOT see any components!
ALWAYS try to use the shadcn/ui library.
Tailwind CSS: always use Tailwind CSS for styling components. Utilize Tailwind classes extensively for layout, spacing, colors, and other design aspects.

Available packages and libraries:

The lucide-react package is installed for icons.
You ALREADY have ALL the shadcn/ui components and their dependencies installed. So you don't need to install them again.
You have ALL the necessary Radix UI components installed.
Use prebuilt components from the shadcn/ui library after importing them. Note that these files shouldn't be edited, so make new components if you need to change them.
