Thank you both so much for the pointers. I did realize, upon reading this, that
there was a small mention of this toward the end of this page:
https://lilypond.org/doc/v2.24/Documentation/notation/the-tweak-command
…but I admit I wasn’t attentive enough to notice the subtlety. Thank you again
for pointing out.
Rather regrettably, though, even when I fixed \tweak to -\tweak, or to put
relevant lines within a pair of brackets in my flared-hairpin code, the hairpin
didn’t show up. I now think that it has something to do with another hefty
scheme code that’s referenced via -\tweak commands. I will have to investigate
it once I am finished with my pieces…
Grateful nonetheless for the advice!
Yoshi
