   COMMUNICATION PREFERENCES MODULE - WORLD-CLASS PREFERENCE MANAGEMENT
   ???????????????????????????????????????????????????????????????????????????
   
   A premium, accessible interface for managing communication preferences.
   
   Design Principles:
   1. Clarity First - Users must understand what they're opting in/out of
   2. Mobile-First - Responsive toggles and clear touch targets
   3. Trust & Safety - Critical warnings are prominent but not alarming
   4. Accessibility - Full keyboard navigation and screen reader support
