/**
 * Reisefroh Rotating Banner - PSYCHOLOGICAL UI DESIGN
 *
 * Design principles applied:
 * - Color psychology (vibrant gradients per category)
 * - Visual hierarchy (F-pattern reading)
 * - Attention triggers (subtle animations, micro-interactions)
 * - Urgency indicators (badges, scarcity cues)
 * - Pattern interrupts (varied colors, textures)
 * - Social proof (trending badges)
 * - Accessibility (WCAG AA contrast, reduced motion)
