This example demonstrates how to add a tooltip to a React component using Tippy.js. It renders a dark blue message box and displays a tooltip containing formatted text with an emphasized word when the user hovers over it. The code uses the `Tippy` component from `@tippyjs/react`, which wraps a `<div>` element and accepts a `content` prop for the tooltip’s HTML. The React app is powered by `react` and `react-dom` UMD builds, with Tippy.js and Popper.js loaded via CDN for positioning.
