svg fundamentals
This example demonstrates the foundational elements of SVG rendering within a bare HTML page. It shows a minimal document structure with empty `<head>` and `<body>` tags, relying on CSS and JavaScript for any visual output. The code uses vanilla HTML and does not import external libraries or frameworks, focusing purely on the core markup syntax. It serves as a starting point for understanding how SVG integrates into standard web documents, though it currently renders no visible graphics or interactive elements.
