/**
 * WC AI Chatbot — Widget Styles
 * Premium redesign: inspired by Claude.ai, Intercom Fin, Linear.
 *
 * Design principles:
 * – Dark confident header (not brand-colored) for trust & professionalism
 * – Asymmetric bubbles: AI = full-width content card, User = compact colored
 * – 4-layer shadow system for genuine spatial depth
 * – Spring-eased micro-animations on every interaction
 * – 15px / 1.65 line-height for maximum readability
 *
 * @package WCAIC
 * @since   1.2.0
