Jetshree/PrepTalks ? reverse-engineered prompt

Build me a clean, modern landing page for PrepTalks in this Next.js app.

I want the homepage to feel polished and professional, with a clear hero section, a short explanation of what the site is for, and a few simple sections that help someone quickly understand the value and get started. Make it responsive, easy to read, and visually appealing on both mobile and desktop. Use the existing Next.js setup and keep the implementation straightforward so it’s easy to edit later.

Please make the page look complete, not like a default starter app, and feel free to look up current Next.js best practices online if you need to. If there’s anything in the project structure that suggests a different setup, follow that and keep the app working smoothly.
