GRB 211211A (left) and GRB 230307A (right) optical/near-infrared observations compared to the best-fit interpolated light curve characterized by the parameter values reported in the posterior plots under the assumption of a weak r-process ejecta composition. The r and i observations at 0.27 days are artificially separated by ±0.01 days for visual clarity.
