/**
 * FAB Popup Chat Styles - Version 3 (Complete Rebuild)
 * 
 * This CSS uses HIGH SPECIFICITY selectors to completely override frontend.css.
 * The selector .webtron-ai-chat-popup-content .wfab-chat beats any selector
 * from frontend.css since it's more specific and loads later.
 * 
 * Architecture:
 * - All selectors prefixed with .webtron-ai-chat-popup-content for specificity
 * - Uses .wfab-* classes for styling (never raw .webtron-ai-* for layout)
 * - NO !important tags - wins through specificity alone
 * - Complete reset of all inherited styles
 * 
 * @version 3.0.0
