- Automatically creates /opt/lecommit/frontend/.env.prod from GitHub secrets
- Eliminates need for manual file creation on production server
- Ensures secrets are always up-to-date on deployment
- Single source of truth for production environment variables
- Fixes 'no such file or directory' error during container startup
