Demonstrates:
  - ChaseCamera node tracking a moving target with smoothed offset
  - half_life Property as the visible knob (lag vs snap)
  - The trail effect: camera lags behind so player motion reads naturally

    A / Left         : Turn left
    D / Right        : Turn right
    Q / E            : Increase / decrease half_life (snap <-> heavy lag)
    R                : Snap camera to rest pose (no smoothing)
