KEY FEATURES
================================================================================

FEATURE 1: Waypoint Patrol (Single Room)
- NPCs follow predefined waypoint coordinates (3-8 range)
- Sequential or random waypoint selection
- Optional dwell time at each waypoint
- Validates waypoints are walkable
- Falls back gracefully to random patrol if invalid

FEATURE 2: Cross-Room Navigation (Multi-Room)
- NPCs patrol across multiple connected rooms
- Automatically transitions between rooms
- Pre-loads all route rooms
- Validates room connections
- Loops infinitely through all rooms

================================================================================
BACKWARD COMPATIBILITY
================================================================================

✅ FULLY BACKWARD COMPATIBLE
- Existing scenarios work unchanged
- New features are opt-in
- No breaking changes
- Random patrol still works
- Can mix old and new configurations

================================================================================
NEXT STEPS

2. Read README_NPC_FEATURES.md (10 min)
3. Read NPC_FEATURES_COMPLETE_SUMMARY.md (10 min)
4. Decide implementation priority
