All sorted now.
Thanks! Well (tail between legs), the problem was not the template that was being called, but a template being "included" inside that template. That second template is loaded based on a few "if" statements, and a bug/flaw in my logic (undetected until now ... code in place for months), failed to load a valid template file. Didn't get error messages (no access to "post mortem" page as I don't run the app on a web servrer) sufficient to point me to the real cause and I was chasing red herrings for a while.
Message for others: when in similar circumstances, look for issues not only with the first-called template, but any templates "included".
Re "alpha" ... well, simple inertial. The Django stuff I do is not on a web server but on my PC. I use Django to construct static HTM files, and other things, from content held in the database. I simply copy the HTM files to the server on change. Sort of taking the approach "it works, don't break it on purpose". I'll do an upgrade to current version this week.
