This example demonstrates a minimal HTML page that renders the text "Hello HTML" in large, centered type using CSS, while also logging "Hello JavaScript!" to the browser console. The body’s `font-size` is set to 13em via inline styles, and the JavaScript runs immediately in a script tag. It uses no external libraries, relying solely on standard HTML, CSS, and the browser’s native `console.log` API to illustrate basic web page structure and interaction.
