🌾 The Tragedy of the Commons (2D)

This 2D companion drives the same logistic-regrowth grazing model as the 3D version through a plain top-down canvas view: a grid of grass cells regrows toward full biomass on its own, coloured herder dots seek out and graze the richest nearby cell, and the same herders/harvest-rate/regrowth-rate sliders and sustainable-quota toggle let you watch the pasture either collapse under unrestricted access or stabilise under a shared limit — read directly off the biomass bar and collapse-countdown readout instead of a rotating 3D scene.
