vercel-fieldeng/platforms-custom-domains ? reverse-engineered prompt

Build me a clean Next.js site for a product about custom domains on a platform. I want it to feel polished and modern, with a simple homepage that explains how custom domains work, why they matter, and how a user can connect one to their project.

Please make it look like a real v0 style app, responsive on mobile and desktop, with a strong hero section, a few clear feature sections, and a nice call to action. If it makes sense, include a small dashboard style area where someone can see domain status, add a domain, and view basic setup steps like DNS and verification. Keep the copy friendly and easy to understand.

Use the existing project structure and make whatever components and styling you need. If you need current details for Next.js or v0 patterns, look them up online first.
