"""Split screen for the projector (#17): patient on the left, doctor on the right, clock on top.

Left: the patient web app in an iframe when `PATIENT_WEB_URL` is set (React app, e.g. http://localhost:5173),
otherwise the console's fallback web chat. Right: compact doctor panel polled every 2 s with a red banner
on a new acute alert.
