## [3.0.302] - 2026-10-01
First release, for AR 51 Unity SDK 3.0.3.2.

### Added
- `HeadsetCalibrator`: lines up the headset's world with the AR 51 capture space automatically while the wearer moves; recovers by itself after a headset recenter or tracking loss.
- `State`, `Hint`, `StateChanged` and `HintChanged`, so an app can tell the wearer what to do.
- `CalibrationHintPanel`: optional in-headset panel that shows the hint only when the wearer can help, with editable texts.
- `Headset Calibrator` prefab (calibrator + hint panel).
- Calibration Demo sample: ready scene with two small example scripts.
