kargulstudio/sales-crm ? reverse-engineered prompt

Build me a clean, modern sales CRM website from this starter.

I want a polished landing page and a simple app feel, with a hero section, key benefits, a feature overview, and a clear call to action for booking a demo or signing up. Keep it responsive, fast, and visually consistent with the existing design system in this repo, and follow the project rules before making any components or pages. Use the SEO setup properly so the page title, description, sitemap, robots, and social preview all make sense. If you need current Next.js guidance, look it up online.

Please make it feel like a real product site for a small sales team, with clean typography, strong spacing, and a premium SaaS look. Keep the build simple and production ready, and make sure everything works nicely in the browser with good metadata and accessibility.
