Variable: Bone2D

const Bone2D: Trait<{ name: string; }>

Bone2D — marks an ECS entity as a bone of a SkinnedSprite2D rig. The bone's real state is the entity's own Transform (posed by the gizmo/Inspector, or keyframed via Animator — a 2D bone is just an entity, so animation is free); this trait only carries the bone's name, which must match a bone in the rig's .rig2d.json. skin2DSystem walks the child Bone2D entities under a SkinnedSprite2D root (via EntityAttributes.parentId) to build the live pose.

Deliberately distinct from the 3D Bone trait so syncBones never touches it and the 2D/3D skinning paths stay cleanly separated. Fully SCALAR.
