This is being worked on, too. At some point in the future, any games you’ve uploaded will look like they do on your local interpreter. Even if it was a deal breaker, it wouldn’t be one forever.
As a general rule when I make games with TADS: I try to make the game work well on QTADS, Parchment, a screen reader, and on a basic terminal. All the fancier output formatting is just a bonus to me, and I try not to lean into it too much.
EDIT: More importantly: Welcome aboard! It’s always fun to have another TADS 3 dev!
