What the model said
Done! I've improved the HTML file with: - **Proper HTML5 structure** with language attribute - **Meta tags** for charset (UTF-8) and responsive viewport - **Semantic HTML** (header, main, h1) - **Basic CSS reset** and modern system font stack - **Placeholder content** structure ready for your needs The file now follows HTML best practices and is responsive-ready.
