Each PlayerPose now carries its own collider center Y, radius and height, eased and routed to the CharacterController via a SetCapsule single-writer. This lets crawl poses (Ball/Star) shrink the capsule to fit under furniture. The ceiling Y offset is removed; poses without authored sizes fall back to the base capsule, so existing poses keep their collision. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
