What Breaks — Contrarian Correction

Most guides: upload side photo to AI posture app. Backwards: you get score after slouching an hour, and you sent home video to server. Correct: local WASM BlazePose gives instant feedback, no upload. Skip calibration and 6'2" gets false alerts (height changes geometry 18%). Skip slouch accumulator and you waste 12 min/day breaking when already good.

60° forward head = 60 lbs extra on your neck. Your browser can measure it without uploading video — MediaPipe runs 100% local.
