 * ImuChartView — rolling time-series chart for 6-axis IMU data.

 * Two stacked subplots (accel + gyro), each showing 3 colored channels
 * across a rolling time window ending at the current clock. Canvas 2D,
 * redraws on every `clock.on('tick')` for smooth scrubbing.
 *
 * ## Data format
 * JSONL lines of shape `{ ts: number, data: [ax, ay, az, gx, gy, gz] }`
 * (stride=6). Recommended source rate: 50–200 Hz.
 *
 * ## Hooks used
 * `useMergedTrack` to keep the current + neighboring chunks merged, then
 * imperative Canvas drawing driven by `clock.on('tick')` — no per-frame
 * React re-renders.
