This example demonstrates a minimal HTML page that displays the text “Hello HTML” in large, centered type. It pairs static CSS styling with a JavaScript console message, illustrating the basic integration of markup, style, and scripting. The page uses inline `<style>` for the bold 13em font and a `<script>` tag with `console.log()` to output “Hello JavaScript!” to browser developer tools. No external libraries are loaded; the example relies entirely on native HTML, CSS, and JavaScript APIs.
