I deemed it not-worthy of adding text resources / visuals as not many people end up using it. It's not really worth the extra effort to log decoration dimensions and come up with a grid, or come up with base boundaries.
Even QR I/O of bases isn't really worth it imo, can generate them ingame (plus the stored structure isn't the same as the packed QR). If the PID was saved in the QR we could have made up a decoder for shiny value logging, but nah, it only contains a boolean if it is shiny or not in addition to the IVs/EVs.
