🤖 AI Behavior System + Sound Manifest
✅ NEW SYSTEMS: 1. AnimalBehavior.js - Wander, Flee, Follow, Glowing Eyes 2. NPCIdleBehavior.js - Idle animations (hat fix, sweat wipe) 3. ANIMAL_SOUND_MANIFEST.md - 40+ sound mappings 🎮 AI FEATURES: - Smooth movement (not grid-based) ✓ - Flee from player (100px range) ✓ - Follow with delay (cargo animals: llama, horse, donkey) ✓ - Glowing eyes in darkness (NOIR EFFECT!) ✓ - Neon pink/green eyes visible at distance - Perfect for 'eyes in forest' atmosphere 👤 NPC FEATURES: - Random idle animations every 3-8 seconds - Fix hat, wipe sweat, look around, scratch head - Gronk-specific: coin counting, item polishing 🔊 SOUND SYSTEM: - Kenney pack mapping for 23 animal sounds - Footstep variations (mud, grass, cobble) - Noir sound design: muffled distant sounds + reverb DEMO: 56/60 sprites (93%)! Next: 4 remaining sprites + integration testing
