perfectdev1121/dekang — reverse-engineered prompt

Build me a clean, modern TypeScript web app for a project called Dekang. There isn't a README or detailed product spec yet, so keep it simple and make it feel like a polished starter product I can customize later.

I want a nice responsive landing page with a clear hero area, a few sections for what the product is, benefits, and a call to action, plus a basic app layout that could grow into a real dashboard later. Use the existing frontend setup in the repo, keep the styling consistent, and use reusable components rather than one giant page.

Make sure it runs locally, passes the normal lint and type checks, and is ready to deploy with the deployment config that's already here. If you need current docs for the tools in this project, look them up online. Please leave the code tidy and easy for a beginner to edit.
