/* ============================================================================
   Phase 9.2: Wordle-Inspired Design (Satirical "Hunt" Theme)
   ============================================================================

   This section implements a satirical take on Wordle's design for the
   Daily Image Hunt game. Key features:
   - Tile-based attempt counter (inspired by Wordle's grid)
   - Color-coded feedback (green = hit, gray = miss)
   - Flip animations for revealing attempt results
   - Bounce animations for win celebrations
   - Pop feedback for interactions

   Design Philosophy:
   - Recognizable as Wordle-inspired but clearly different
   - Uses "Hunt" color variations (not exact Wordle colors)
   - Maintains WCAG 2.1 AAA accessibility standards
