Mediapipe.js for browser eye detection in meditation app

Running eye-closure detection locally in the browser is the smart differentiator here — privacy-first verification without uploading video. Coupling that with Stripe-backed stakes and a single grace day creates a blunt but effective accountability loop. It isn't a new product category (hello Beeminder/Pact), so the real value will come down to how robust the CV is in varied lighting, anti-spoofing, and false-positive handling.
