What the model said

Done! I've improved 0.html with:

- **Proper HTML5 structure** with `<html>`, `<head>`, and `<body>` tags
- **Meta tags** for character encoding (UTF-8) and viewport responsiveness
- **Language attribute** (lang="en")
- **Basic CSS styling** for readability (clean typography, centered layout)
- **Content** with a heading

The file is now a valid, modern HTML document with web best practices.
