Indeed, I had simply assumed it was prohibited (without ever having
seen a source), and I simply assumed there'd be a source were I to
look for it. Only when she said, with complete surety, that there was
no such prohibition, was I brought short.

Is there any halachic statement, regarding tzenua or any other issue,
that one could use to justify this meta-letter-of-halakha concept of
tzenua? I can think of "Do what is good and right...", but other than
that...
