🦕 Dinosaurs (2D): Herd & Predator-Prey Behaviour Lab

This 2D companion runs the exact same herd and predator-prey rules as the 3D version — herbivores graze on dropped food and collect eggs, while carnivores continuously steer toward the nearest herbivore straggler — but draws everything as flat "paper cutout" shapes directly on a Canvas2D context instead of a WebGL scene. A live side panel adds something the 3D build doesn't show: population, herbivore/predator split, eggs collected and the herd's average speed, updated ten times a second, plus a third slider — Predator drive — that scales how hard carnivores accelerate toward prey, making the safety-in-numbers effect of herding directly tunable.
