Hand-built layered vector Byte, animated in real time: idle breath, blinking, secondary bob on the headphones and feet, and a spring react-burst on every emotion change. This is how the companion will move in-app — tap an emotion or let it auto-play.
Same rig, same character — only the pose channels (eyes, lids, brows, gaze, mouth, arms, tilt, energy) change per emotion, spring-eased. Feet + headphones carry a little secondary motion so it reads alive, not swapped. In production this becomes a Rive state machine driven by the app.
