/**
 * Apex Chatbot — Front-End Stylesheet
 *
 * HOW TO CUSTOMIZE:
 *   All visual variables are in the :root { } block below.
 *   Change colors, fonts, spacing, and border-radius there.
 *   Do NOT edit Divi's global CSS — all selectors here are namespaced
 *   with .apex-chatbot-wrap to prevent conflicts.
 *
 * SECTIONS:
 *   1. CSS Custom Properties (variables)
 *   2. Outer wrapper & card
 *   3. Header
 *   4. Progress bar
 *   5. Message feed
 *   6. Option buttons
 *   7. Lead form
 *   8. Booking step
 *   9. Typing indicator
 *  10. Responsive overrides
