Web Serial-based wizard that takes a non-technical user from unboxed ESP32-S3 to streaming CSI in under 5 minutes. 8-step state machine: browser check → connect → flash firmware (esp-web-tools) → provision WiFi → detect node → guided calibration → placement guidance → complete. Includes sessionStorage persistence for resumability across page refreshes, live CSI waveform during calibration, human-friendly error messages for all failure modes, and comprehensive Jest test coverage (34 tests).
