Caption: Figure A1.

The RGB composite color image of the most massive protocluster core (0217A). The red, green, and blue channels correspond to the JWST/NIRCam F444W, F277W, and F150W filters, respectively. Member galaxies are overlaid as open circles: massive SFGs (M* > 1010M) in yellow, low-mass SFGs (M* < 109M) in cyan, and quiescent galaxies (QGs, including both passive galaxies and poststarburst galaxies) in red.
