Shoulder vertical position (raw, normalized 0–1; 0 = top of frame)

Waiting for pose…

Breathing waveform (bandpass 0.1–0.5 Hz; % of frame height; inhale = up)

Waiting for pose…

Filter has a transient on startup — expect about 5–10 seconds of warmup before the trace stabilizes. Sit still: head/torso motion can swamp the breathing signal.
