I have never been able to use .jigdo or understand jigdo, sadly I do not know
how to use them. ISOs I understand.
I found this link, but do not understand what it is saying. It suggests "these
images may also be written directly to a USB stick" but does not show how to do
this.

If you can show the commands that produces a very large ISO from a BD .jigdo
file, then that would help.
Something like: (??)
# wget
https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dlbd/debian-12.5.0-amd64-DLBD-1.jigdo
# cp
https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dlbd/debian-12.5.0-amd64-DLBD-1.jigdo
/dev/sdf (but I guess this does not work?)
