- JointComponent: type, target UUID, per-body local anchors, hinge axis
+ angle limits (data only, zero Jolt deps)
- PhysicsWorld::SyncConstraints: create/remove/rebuild on snapshot
change; body rebuild contagion via invalidated-bits list; target
resolved lazily by UUID each sync (no two-pass load needed)
- Jolt FixedConstraint/HingeConstraint/PointConstraint in
LocalToBodyCOM space (anchors minus shape COM); fixed frames lock
creation-time relative pose; hinge axis aligned across bodies
- Inspector: Joint section with target entity name dropdown
- Serialization: Joint map with UUID target, as<T> fallbacks
