This example shows a minimal HTML page that prints a message in a black-banded heading and logs a computed value to the console. It demonstrates how CSS styles an `h1` element with white text on a black background, while a small inline JavaScript script assigns a variable, increments it, and outputs the result via `console.log`. The page relies on plain HTML, CSS, and JavaScript—no external libraries or frameworks—making it a bare-bones starter for understanding basic web rendering and script execution.
