"""
sync_audio_to_prod.py — Sube a PROD los mp3 de TTS ya generados/enlazados en
local (fea_audio_done=1) y fija el meta fea_audio_url en prod.

Prod (134.0.10.170) tiene glibc rota: scp/sftp NO funcionan (connection closed).
Workaround: subir el binario por stdin de ssh ("cat > ruta"), igual que el resto
de scripts que tocan ese servidor (ver feadulta-server-glibc-rota.md).

Uso:
  python3 sync_audio_to_prod.py --carta 54254            # sincroniza toda la cola de la carta
  python3 sync_audio_to_prod.py --ids 912,919,3001        # ids concretos
  python3 sync_audio_to_prod.py --carta 54254 --dry-run   # solo plan, no toca prod

Rollback (despublica en prod lo que este script publicó):
  python3 sync_audio_to_prod.py --rollback --carta 54254
  python3 sync_audio_to_prod.py --rollback --ids 912,919
