- Fix critical bug in PlanckDebugDraw.js where circles were drawn at body center instead of local positions
- Add DEBUG_DRAW_SENSORS support with orange styling and no outlines
- Fix Chuck's sprite positioning to align with physics body center (pivot adjustments)
- Correct fixture Y coordinates so Chuck stands upright instead of on his head
- Position foot sensor correctly below legs for proper ground detection
- Remove cyan crosses and make yellow center-of-mass crosses smaller
- Make debug lines thinner for cleaner visualization
- Replace Box2D.js with Planck.js physics engine
- Update all require paths from 'Lib/Vendor/Box2D' to 'Lib/Vendor/Planck'
- Convert Box2D contact listeners to Planck.js event system
- Fix all method name capitalization (Get* -> get*, Set* -> set*)
- Update collision detection system for Planck.js compatibility
- Server now starts successfully and basic physics working
- Character can land on platforms - core physics functional
Major milestone: Game now running on modern, maintained physics engine
