Spin Glass Lattice: Bond Disorder & Metropolis Relaxation (2D)

This 2D companion runs the same Edwards-Anderson spin-glass model as the 3D/WebGL original — Ising spins on a square lattice with randomly signed nearest-neighbour bonds, updated by Metropolis Monte Carlo — but renders it on a plain Canvas 2D surface and adds a control the 3D version fixes at 50/50: the antiferromagnetic bond fraction p. Drag p from 0 (a plain ferromagnet, every bond agrees, no frustration) up to 0.5 (maximum disorder, the classic spin glass) and watch red frustrated bonds and the order parameter q appear in real time, rather than starting already fully disordered.
