- MoveToAnim x/y/z are absolute target positions, not offsets: objects are
authored in their hidden state and tweened to the visible position
(e.g. the LANGUAGES title -500 -> 20). JPCSP's offset treatment is wrong.
- Register unlabeled child entries (animation records) under the 'children'
property with a synthetic zero-padded name, so BaseAnim.play can reach
them. Previously anim containers had zero children and played nothing.
