The only additional suggestion I've received that might possibly make some sense is "is this an issue of login vs non-login shell?" Does that trigger any ideas for anyone?

And possibly of some value, I note that the config of Raspberry Pi OS does not have this problem; connecting via VNC results in an environment where the ulimit -r value is what we need. I tried poking around at the assorted directories but the limits and pam stuff are sufficiently different that it makes no sense to me.
