It is a proof of concept with no scoring behind it yet. What it demonstrates is the instrument set: the camera runs timed face-exam prompts, the microphone drives a live waveform through a Web Audio analyser, the analysing screen draws a globe in WebGL, and a trends view plots each reading against a baseline.
React and Vite, with no server behind it — one client bundle and a hand-rolled History API router. The face step drives getUserMedia through timed prompts; the voice step reads the live MediaStream into a Web Audio analyser; the globe is react-three-fiber over world-atlas topology, code-split and fetched the moment a check begins.
