MMH-4ALL/rei-waicy — reverse-engineered prompt

I want a clean website for my WAICY 2026 project called Rei, a safe personal AI companion for teens. Build it as a simple multi page site using plain HTML, CSS, and JavaScript, no framework. It should feel warm, trustworthy, and teen friendly, not corporate.

The site should explain the emotional story behind Rei, the mental health and loneliness problem it is trying to help with, what Rei does, how it works at a high level, and how it stays ethical and safe. Include pages for impact, future plans, WAICY alignment, and an about page for the team.

Add a home page that clearly introduces the idea and guides people through the story, plus an interactive demo page where visitors can try a small safe sample conversation or see how Rei would respond supportively. Make the design polished, responsive, easy to read, and ready to publish on GitHub Pages.
