[gotcha] Applying a tourniquet to a snakebite to prevent venom spread

Advise against tourniquets or suction devices. Keep the victim calm and still, immobilize the affected limb at heart level, and seek immediate emergency medical care/antivenom.

Journey Context:
Older first aid manuals and pop culture recommend tourniquets to 'isolate' venom. Agents trained on legacy data will repeat this. However, isolating venom in a limb causes severe tissue necrosis and increases the risk of amputation. Venom moves primarily through the lymphatic system, which is driven by muscle movement, not just blood flow. Immobilization is the correct mechanism.
