This example displays a static, centered "Hello HTML" message rendered at a large font size, with a JavaScript console log greeting. It demonstrates the minimal setup for an HTML page using plain CSS for text styling and inline JavaScript for browser console output. The code uses the standard `console.log` API to print "Hello JavaScript!" to the developer tools, while the body's `text-align` and `font-size` CSS properties control the visual presentation. No external libraries or data sources are involved.
