Summary

Render a movement graph on the parent device from the child device's gyroscope/accelerometer telemetry (child phone resting on the bed → baby movement visible).

What to do

Ingest the child's sensor telemetry stream on the parent
Compute a movement/signal metric from accel/gyro
Render a live movement graph
Handle sensor stream interruptions (child moving phone, etc.)

Acceptance criteria

Movement graph updates from child sensor telemetry
Movement metric computation is unit-tested
Visualization widget has golden tests
Handles missing/stale sensor data clearly

Notes

Depends on transport and child-side telemetry
Metric derivation separate from widget for testability
