This fork demonstrates a minimal HTML page that loads no external content and renders an empty document body. It relies on the browser’s default HTML parsing and does not use any JavaScript, CSS, or data-visualization libraries such as D3.js or Three.js. The example contains only the core HTML boilerplate—a `<!DOCTYPE html>` declaration, a `<head>` with a title, and an empty `<body>`—making it a bare starting point for embedding visualizations. The embedded YouTube video is the only media present, but it is not part of the page’s runtime behavior.
