This example demonstrates an asynchronous data-loading and report-generation workflow in a minimal web dashboard. It displays a list of used cars with their make, model, year, and price. The code uses a simulated `getCars()` promise that resolves a hardcoded JSON dataset after a two-second delay, then processes it with `filter` and `map` via the `generateReport` function.
