Key changes:
- Explicitly state image has EXIF orientation stripped (raw/native state)
- Return ONLY the tilt angle, not orientation shifts
- Expect small angles (-45° to +45°), not large ones
- Add safety check: if angle > 45°, likely measurement error
- Simplify examples to show tilt-only measurement
This ensures Gemini returns consistent, sane rotation values regardless
of the item or how the photo was taken, without needing local offsets.
