/**
 * Example demonstrating how to use SwingFXMarkdownWindowPreview
 * to create a standalone Markdown preview window with live updates.
 *
 * <p>
 * Features demonstrated:
 * <ul>
 *   <li>Load Markdown from a File</li>
 *   <li>Launch the preview in its own window</li>
 *   <li>Detect when the preview window is closed</li>
 *   <li>Reopen the preview window on demand</li>
 *   <li>Optionally set dark mode and a custom icon</li>
 * </ul>
 *
 * <p>
 * Example usage of constructors:
 * <pre>{@code
 * SwingFXMarkdownWindowPreview preview = new SwingFXMarkdownWindowPreview(new File("README.md"));
 * }</pre>
 *
 * <p>
 * Example of enabling dark theme:
 * <pre>{@code
 * preview.setDarkMode(true);
 * }</pre>
 *
 * <p>
 * Example of reopening window:
 * <pre>{@code
 * preview.reopenWindow();
 * }</pre>
 *
 * <p>
 * Example of checking if the preview is showing:
 * <pre>{@code
 * boolean showing = preview.isPreviewShowing();
 * }</pre>
 *
 * <p>
 * Example of setting a custom icon:
 * <pre>{@code
 * preview.setIcon("/MD.png");
 * }</pre>
