This example demonstrates a minimal HTML page that displays the text "Hello HTML" in large, centered type, styled via CSS within a `<style>` block. The page also executes a JavaScript snippet that logs "Hello JavaScript!" to the browser’s developer console. The code uses raw HTML, CSS for font sizing and alignment, and vanilla JavaScript with the `console.log` API. This starter serves as a bare-bones illustration of how HTML, CSS, and JavaScript combine in a single file.
