ck-sayan/homura-client ? reverse-engineered prompt

Build me a simple polished website for Homura Client.

I want a clean landing page with a home screen, plus separate pages for a changelog, licenses, a style guide, and the 404 and 401 error pages. It should feel like a real product site, with good typography, responsive layout, images and icons where needed, and a consistent visual style across every page.

Please make the main page easy to scan, with a strong hero section, a short overview of what the client is, and sections for features and updates. The extra pages should match the same look and feel, not feel like separate templates. Use the existing css, js, fonts, and images folders if they help, and keep the whole thing lightweight and fast.

If you need current best practices for the layout or browser behavior, look them up online and follow them.
