`--signer` is what makes this the paid path: the client only sends its payer address when a signer is configured, so without it the orchestrator cannot build a payment challenge and rejects the session with `402 invalid live runner payment signer address`.

The price is unchanged by the overlay: static runners advertise it from `runners.json` (`price_info.price`, USD per hour by default), which both compose files mount. Keep demo sessions short — the meter runs for as long as the socket is open.
