🩹 First-Aid Physics Lab: Bleeding, Blood Flow, Tourniquet Pressure and Triage Decisions

One 3D cut-away mannequin lab that ties Poiseuille r^4 leak rates, a Windkessel pressure waveform, ATLS blood-loss classes, hand and windlass-tourniquet pressure (Laplace strap law, strip load, the venous trap) and a START triage queue together; it differs from the single-topic hemorrhage-compensation, START-triage and tourniquet-training sims by modelling all four as one connected physics chain. Educational model, not medical advice - take a certified first-aid course.
