This example demonstrates a simple pet-selection interface with a large, prominent dropdown menu. The React application uses the `useState` hook to manage the currently selected pet value, which is logged to the console, and a custom `Dropdown` component. The component renders a native HTML `<select>` element, mapping option values and labels from a data array. The ReactDOM library is used to render the `App` component into the page’s root element, with all styling defined in the HTML.
