# Sub2API Docker Deployment Preparation Script
# =============================================================================
# This script prepares deployment files for Sub2API:
#   - Downloads docker-compose.local.yml and .env.example
#   - Generates secure secrets (JWT_SECRET, TOTP_ENCRYPTION_KEY, POSTGRES_PASSWORD)
#   - Creates necessary data directories
#
# After running this script, you can start services with:
#   docker-compose -f docker-compose.local.yml up -d
# =============================================================================
