 * Tests for simple mode functionality including:
 * - Room occupancy cards with WebSocket updates
 * - Activity feed filtering (excluding system noise)
 * - Alert banner appearance and dismissal
 * - Mode toggle between simple and expert
 * - Sleep summary card timing (6am-11am)
 * - Occupancy card pulse animation
 * - Night mode activation based on quiet hours
