Stellar mass and size assembly of simulated compact galaxies at four redshifts: z = 0 (upper left), z = 0.3 (upper right), z = 0.7 (lower left), and z = 2 (lower right). Each panel displays the evolution of stellar mass fraction and effective radius over time. All panels are color-coded by the stellar mass accreted since z = 2, except for the z = 2 panel, which remains uncolored. The vertical dashed black line marks z = 2, while the dashed purple line indicates the redshift corresponding to each sample. The horizontal grey line denotes the 90% stellar mass fraction threshold at the given redshift.
