Fixes #96 - nginx.conf converted to template processed by envsubst at container start - BACKEND_URL env var (default: backend:3000) replaces hardcoded container name - Docker DNS resolver used for dynamic upstream resolution - Dockerfile copies nginx.conf as template to /etc/nginx/templates/ This prevents frontend breakage when users customize container names in their docker-compose.yml.
