"""Shared vision utilities for Reachy Mini apps.

Two layers:
- **Attention** (present + engaged): `Detector` protocol + `AttentionResult`,
  with `MotionPresenceDetector` (zero-dep default) and `VLMAttentionDetector`
  (real engagement via a vision LLM). `build_detector(spec)` picks one.
- **Objects / pose** (optional, heavier deps): `ObjectDetector` (YOLO phones),
  `HeadPoseEstimator` (MediaPipe). Import these directly when needed.
