                         (DE) and dark matter (DM), for which state-of-the-art limits have 
                         so far been obtained from late-time background measurements. We 
                         use the joint likelihood for prereconstruction full-shape (FS) 
                         galaxy power spectrum and postreconstruction Baryon Acoustic 
                         Oscillation (BAO) measurements from the BOSS DR12 sample, 
                         alongside Cosmic Microwave Background (CMB) data from Planck: from 
                         this dataset combination we infer H0 1/4 68.02+0.49 and the 2?? 
                         lower limit ?? > ???0.12, among the strongest limits ever reported 
                         on the DM-DE coupling strength ?? for the particular model 
                         considered. Contrary to what has been observed for the ??CDM model 
                         and simple extensions thereof, we find that the CMB + FS 
                         combination returns tighter constraints compared to the CMB + BAO 
                         one, suggesting that there is valuable additional information 
                         contained in the broadband of the power spectrum. We test this 
                         finding by running additional CMB-free analyses and removing sound 
                         horizon information, and discuss the important role of the 
                         equality scale in setting constraints on DM-DE interactions. Our 
                         results reinforce the critical role played by redshift-space 
                         galaxy clustering measurements in the epoch of precision 
                         cosmology, particularly in relation to tests of nonminimal dark 
                         sector extensions of the ??CDM model.",
