This example demonstrates asynchronous data loading and report generation in a minimal HTML page styled with CSS. It uses vanilla JavaScript with Promises to simulate a network request via `getCars()`, which returns a JSON array of used cars after a two-second delay. The `generateReport` function filters cars by price and formats each entry using `formatCar`, then displays the resulting text in a `<pre>` element. The React framework is referenced only in the README, while the core code relies on native DOM manipulation through `document.getElementById` and no external libraries.
