The receptionist issues a token in five seconds; the patient scans a QR off the monitor — no printer, no paper, no typing. Three views (receptionist console, waiting-room TV, patient phone) stay in lockstep via Socket.IO under 300 ms latency. Estimated wait isn't a guess — it's a rolling average of the last ten real consultations, with an honest "calibrating" label when no data exists yet. Built with Express, MongoDB, and Socket.IO; concurrency is handled by atomic MongoDB counters and status-guarded state transitions, so a double-clicked Call Next is always a clean no-op.
