Burndown = (BAC - target_low)/beta projects time to leave the range. - Local live web dashboard (stdlib http.server + vanilla-JS canvas, no pip installs, offline): in-range indicator, gauge, BAC curve, burndown line. - Prominent safety framing throughout: the band is a comic-strip joke, above every legal driving limit, not health/safety advice. Note: deliberately corrects the brief's r=TBW/weight to the blood-water form to hit the brief's own stated anchors (documented in config.py/bac_model.py).
