Mechanism of formation of a condensate composed of scaffolds and clients (67% 3-valency scaffolds + 33% 2-valency high-affinity clients) at a value of the normalized inverse interaction strength equal to 0.85 (dashed line in Fig. 3A). Each panel gives a plot of the condensation order parameter for scaffolds (red), $Q^S\left(L\right)$, and clients (blue), $Q^C\left(L\right)$, versus the direction of the largest dimension, $L$, of the simulation box, as well as the value of the relative enrichment of scaffolds over clients in the newly formed condensates ${\chi }_{S/C}$. Simulation snapshots (scaffolds as red spheres and clients as blue spheres) for the different stages of the condensate-formation process are also provided: (A) initial well-mixed configuration, (B) nucleation, (C) growth, and (D) equilibrium condensate.
