What the model said
Done! I've improved the HTML file with: - **Proper structure**: Added `<head>` and `<body>` tags with correct nesting - **Better metadata**: Moved meta tags to the `<head>` section - **Meaningful title**: Changed from "0" to "Welcome" - **Basic styling**: Added a clean CSS style block with system fonts, readable layout, and color scheme - **Content**: Added a heading and introductory paragraph - **Proper formatting**: Added indentation for clarity The file is now a complete, valid HTML5 document ready to use.
