- Engine.Physics (JoltPhysicsSharp) integrated into CortexEngine.App
- 4 cubes: DynamicBox, mass proportional to scale, fall from height 5-10
- 3 spheres: DynamicSphere, mass 1.5, fall from height 7-12
- Floor: StaticBox (20x0.5x20), friction 0.8
- Torus knot + grid: no physics (visual only)
- Physics bodies initialized lazily on first frame (IsInitialized flag)
- e.Set() moved outside world.Each to avoid mutation during iteration
- physicsWorld.Update + SyncTransforms every frame
- Removed manual rotation — physics handles movement now
- Camera at (0, 5, -15) for better view of falling objects
- 0 validation errors, ~1300 FPS
