### Payload shape (example)

```json
{
  "type": "angles",
  "timestampMs": 1730000000000,
  "frameId": 421,
  "angles": {
    "left_knee_deg": 92.4,
    "right_knee_deg": 95.1,
    "left_hip_deg": 78.0,
    "right_hip_deg": 79.2
  }
}
```

Angle naming depends on the skeleton definition used by the engine and may evolve with V3 improvements.
