Automated testbook script that validates the full portrait pipeline on a body:
- Set orientation to portrait via experience library API
- Wait for hydrabody tick to sync
- Verify Sunshine config has VDD output_name
- Verify Sunshine app cmd has -windowed -ForceRes
- Start stream, verify capture size 1080x1920 in Sunshine logs
- Restore landscape
Catches regressions without manual testing. Should be runnable from neoremote via hydracluster exec.
