 * - Better integration with GNOME desktop environments
 * - Enhanced screenshot and visual validation capabilities
 * - Improved error handling and reporting
 * 
 * Requirements:
 * - Uses MCP Playwright server for all browser interactions
 * - GNOME session display integration
 * - WordPress error detection before each test
 * - Comprehensive evidence collection through screenshots
