This example shows a simple React app that renders two text elements: a large "Hello React!" message and a smaller "...with CSS" line in rebeccapurple, based on the CSS Colors from Mozilla documentation. The main component uses JSX within a `<g>` element, though the code does not employ SVG-specific behavior. Styling is handled entirely through an external stylesheet (`index.css`), which sets font sizes and text alignment, while the React DOM library mounts the component to the `#root` div. The page loads React and ReactDOM from a CDN, and the bundled script runs client-side.
