I reprinted the PDF with "Actual Size" scaling using the NokoPrint app and the settings below.
Before I realized I had the sizing wrong, I did retry the toner transfer of the front silkscreen, and it mostly worked, although the cross and some of the letters did not come thru. The areas of toner that didn't transfer properly, I filled in with marker. I can try again with the correct sizing tomorrow, which should help, although the cross probably didn't have enough direct heat applied to it to transfer.
