/**
 * JointAngleView — 2.5-D stick-figure of a 7-DoF serial arm.
 *
 * Layout (side view):
 *  • joint[0] `shoulder_pan`    — base yaw, drawn as a rotating pedestal ellipse
 *  • joint[1] `shoulder_lift`   — first planar hinge
 *  • joint[2] `elbow`           — second planar hinge
 *  • joint[3] `wrist_1`         — third planar hinge
 *  • joint[4] `wrist_2`         — end-effector yaw (affects wedge width)
 *  • joint[5] `wrist_3`         — end-effector roll (wedge rotates)
 *  • joint[6] `gripper`         — parallel-finger opening width
 *
 * Data shapes with other DoF counts are still drawn by chaining the first
 * four available angles as planar hinges; the base pedestal, wrist details
 * and gripper are only shown when their indices exist.
 *
 * ## Data format
 * JSONL lines `{ ts: number, data: number[] }`. Stride is inferred from the
 * first sample. Recommended source rate: 30–250 Hz.
 *
 * ## Hooks used
 * `useMergedTrack` + `useTrackSample` (lerp) + `useClockValue` for React
 * paint. No Canvas — the arm is plain SVG so transforms stay cheap and
 * crisp at any zoom level.
