🌡️ Sol-Gel Transition: Bond Percolation, Gel Point and Modulus (2D)

A square network of monomers whose bonds form at random as cross-linking proceeds. Raise the cross-link probability by hand or let it cure on its own and watch separate clusters merge into one spanning gel at the percolation threshold. Voltage across the network gives a relative modulus, shown against the distance above the gel point with the universal slope, together with the gel fraction and the cluster size distribution. Four in-page numerical checks.
