- setup.sh generates .env with random ports (10000-59999) on first run,
ensuring WEB_PORT, RELAY_TCP_PORT, and RELAY_UDP_PORT are all distinct
- .env.example documents all available env vars with defaults
- docker-compose.yml already reads from .env via ${VAR:-default} syntax
- Run `bash setup.sh` to generate ports, `bash setup.sh --start` to also
bring up the stack in one step
