72/// Samples the world transform of an ancestor TransformComponent and injects it into the
73/// pipeline channel this component is placed under (TransformMapTranslation or
74/// TransformMapRotation).
75///
76/// `skip` controls how many TransformComponent ancestors to climb past from the pipeline
77/// owner before sampling. The walk starts at the pipeline component and goes up:
78///
79/// - `skip = 0` — the driven TransformComponent directly above the pipeline (same as Pass)
80/// - `skip = 1` — the next TransformComponent above that (e.g. the armature bone above the
81///   InputXR-driven T in a splice topology)
82///
83/// The default is `skip = 1`, which is the common case for head/neck bone rotation splices.
