 * Badge component, build around the same styling as in Vaadin Lumo theme,

 * <ul>
 * <li>Can be used in any Vaadin Flow application without Lumo theme</li>
 * <li>Has an actual Java API</li>
 * </ul>
 *
 * @deprecated This component only supports the Lumo theme. Vaadin 25.1+
 * provides a native Badge component that works with all themes. Will be removed in next
