🐘 Elephant Matriarch Drought Trek: Social Memory, Dehydration Clock and Infrasound Rumble Range Lab

An elephant herd led by a matriarch crosses a Blender-modelled savanna to find water: her age sets which waterholes she remembers, drought sets which are dry, a dehydration clock and heat set the deadline, and infrasonic rumbles (spherical spreading plus attenuation versus noise floor) set how far the herd stays in contact. Includes a Monte-Carlo age sweep checked against closed-form probability.
