/**
 * 999DEX COMPLETE ANIMATION SYSTEM
 *
 * Comprehensive animation coverage for EVERY interactive element
 * Based on pump.fun research (Agent 2) and design system foundation (Agent 9)
 *
 * Version: 1.0.0
 * Date: November 2, 2025
 * Agent: 20 - Complete Animation System Implementation
 *
 * PERFORMANCE RULES:
 * - GPU-accelerated properties only (transform, opacity)
 * - 60fps target on desktop, 50-60fps on mobile
 * - Respects prefers-reduced-motion
 * - Will-change used sparingly
 *
 * COVERAGE:
 * - Button states (hover, active, loading, disabled)
 * - Modal animations (enter, exit, backdrop)
 * - Toast notifications (slide in, auto-dismiss, stack)
 * - Form interactions (focus, blur, error, success)
 * - Number counters (count up effect)
 * - Progress bars (smooth filling)
 * - Micro-interactions (copy, hover tooltips, badges)
