This example demonstrates the use of SVG shapes and colors styled through CSS, creating a minimalist visual composition. The page loads an empty `<body>` element with a linked stylesheet, while the code relies on standard SVG and CSS APIs rather than dedicated visualization libraries. The `styles.css` file resets the margin and hides overflow, providing a clean canvas for potential SVG content. The rendering approach is purely declarative, with no JavaScript or data binding visible, focusing on the foundational relationship between markup, styling, and spatial layout.
