Vivvidai/vividsites ? reverse-engineered prompt

Build me a polished website for this free library of cinematic website prompts from vividsites.

I want a clean landing page that shows the free prompts, explains how to use them, and makes it easy to browse by category like landing pages and hero sections. Each prompt should have a nice preview card with an image, a short description, and a link to open the prompt or live demo. Include a strong hero section, a simple nav, and a clear call to action to browse the full library or copy a prompt into Cursor, Claude Code, or Codex.

Make it feel premium and visual, with smooth motion, modern typography, and a cinematic style that matches the previews. It should work well on mobile too.

Keep the experience simple and fast, and use the provided assets and prompt content where possible. If you need current docs or best practices for the animation or layout, look them up online.
