Air 2 Pro y+z head axis

[AdamRaphael]

What happened

When playing SBS video on XREAL Air 2 Pro, head tracking is detected but the rotational axes are not all handled correctly:

• Yaw / left-right head movement works correctly.
• Pitch / looking up and down is detected, but the direction is reversed.
• Roll / tilting the head toward either shoulder does not appear to be detected at all.

The SBS image itself appears visually correct.

What you expected

I expected all three rotational axes to track correctly:

• Turning left/right should move the view correctly.
• Looking up/down should move the view in the matching direction.
• Tilting the head left/right should produce corresponding roll movement.

Steps to reproduce

1. Connect XREAL Air 2 Pro to the phone by USB-C and open NeoXR.
2. Play an SBS video and enable head tracking.
3. Turn head left/right: yaw works correctly.
4. Look up/down: pitch tracking works, but is inverted.
5. Tilt head toward either shoulder: no roll movement is detected.
