Eurasian Lynx Snow Stalk Lab (2D): Stealth, Detection & Energetics

This 2D companion turns the 3D lynx scene's decorative WebGL walk-cycle into an actual predator-prey stalking model: a finite-state creep/sprint controller whose movement speed doubles as the noise signal driving each hare's probabilistic detection radius, a snow-depth parameter that taxes the lynx's energy budget per metre travelled and caps its top speed, and a hare-vigilance parameter that widens the detection radius independently — so the two sliders create a genuine trade-off between how boldly a lynx can move and how much energy it can afford to spend finding out.
