Starling flock and hawk simulation in Three.js

DeepSeek V4.1 Flash-1017, DeepThink on, Three.js. 5,000 starlings and a hawk, all from one prompt. > Boids with a spatial hash grid > The flock folds, splits and merges on its own > The hawk dives into it, or you steer it with your mouse > The lake reflects the whole flock The sun glow is way too blown out, but the flock motion is legit. (Extremely laggy because I'm running this on my humble 2019 Acer Nitro 5.)
