2. I only install Grub the *first* time I do a Debian install.
By poor design Grub puts the current install first on menu.
When experimenting with configuration as I do, the least
likely install to be functional is the latest.
This requires me to run update-grub on the "good" install.
That's ok. I tend to be more promiscuous; usually on a whim, like
wanting to put a particular entry at the top of GRUB's menu list.
When you do 'update-grub' do you still get no "set root=" line for the
SD card in the grub.cfg?

I don't know how many times I've *MIS*read that last sentence ;<
Mentally I was correcting non-existent typos, thus totally garbling it.
I just spent several hours wandering thru grub files and loosely related
documentation.
I've ended up at
www.gnu.org/software/grub/manual/grub.html#Multi_002dboot-manual-config
which says "Currently autogenerating config files for multi-boot
environments depends on os-prober and has several shortcomings. ..."
I also discovered there that placing a customized grub in its own
partition is not only possible, but recommended in some situations. I
had read somewhere that that option had expired with grub-legacy. That,
although taking much time to understand, will solve a *MESS* of grub
problems for me ;/
