"""
DETECTOR AUTOMÁTICO DE MUERTES - VPS READY
==========================================

Estrategia final:
1. Usar transcripción para encontrar candidatos de muerte
2. Extraer frames en esos timestamps
3. Usar OCR básico + heurísticas de validación
4. Generar highlights de los momentos confirmados

Optimizado para correr automáticamente en VPS sin intervención.
