Previous prompt only measured text baseline angle from horizontal (-45° to +45°),
missing that text can be vertical/sideways, requiring larger rotations (up to ±180°).
New guidance:
- Measure TOTAL rotation needed to make text horizontal and readable
- Account for both chassis tilt AND text orientation (horizontal vs vertical)
- Example: 22° tilt + 90° vertical text = 112° total rotation
- Allows full -180° to +180° range instead of limiting to ±45°
