Footbillion.im uses the shared player skeleton with the source idle, kicking,
goalkeeper dive and celebration clips. Kit textures and replay choreography
are authored for Footbillion.im. Goalkeeper right-side dives mirror the source
left-side animation; horizontal striker root motion is scheduled to meet the ball.
