/**
 * Example demonstrating how to use SwingFXMarkdownTabbedPreview
 * to add a live-updating Markdown preview as a tab in a JTabbedPane.
 *
 * <p>
 * Features demonstrated:
 * <ul>
 *   <li>Create the preview tab using a File</li>
 *   <li>Add the tab to a custom JTabbedPane</li>
 *   <li>Launch the preview</li>
 *   <li>Optionally set an icon for the tab</li>
 *   <li>Toggle between dark/light themes</li>
 *   <li>Change the previewed file or Markdown string dynamically</li>
 *   <li>Dispose resources when done</li>
 *   <li>Check if the preview is currently visible</li>
 * </ul>
 *
 * <p>
 * Example usage of constructors:
 * <pre>{@code
 * // From a File
 * SwingFXMarkdownTabbedPreview preview = new SwingFXMarkdownTabbedPreview(tabbedPane, new File("README.md"));
 *
 * // From a String
 * SwingFXMarkdownTabbedPreview preview = new SwingFXMarkdownTabbedPreview(tabbedPane, "# Hello Markdown!");
 * }</pre>
 *
 * <p>
 * Example of setting an icon:
 * <pre>{@code
 * Icon icon = new ImageIcon(getClass().getResource("/MD.png"));
 * preview.setTabbedPaneIcon(icon, 16);
 * }</pre>
 *
 * <p>
 * Example of switching theme:
 * <pre>{@code
 * preview.setDarkMode(true); // Enable dark theme
 * }</pre>
 *
 * <p>
 * Example of replacing the content later:
 * <pre>{@code
 * preview.setCurrentFile(new File("CHANGELOG.md"));
 * preview.setContent("# New Content");
 * }</pre>
 *
 * <p>
 * Example of checking if preview is showing:
 * <pre>{@code
 * boolean showing = preview.isPreviewShowing();
 * }</pre>
 *
 * <p>
 * Example of disposing resources:
 * <pre>{@code
 * preview.dispose();
 * }</pre>
