In Japanese, you can get some visual puns depending on the writing system employed. That's harder to do in alphabetic language. The use of italics, bold, and underline font styles also extend the Latin alphabet.
You don't list contact info on your profile page to contact you with, but I'd love someone (other than Fable/a bot) to work on this with, and you're clearly a like minded individual, so reach out
I periodically see some misinformation here and elsewhere about writing systems, so I thought it opportune to post Omniglot. This old site (online since 1998) has just about all of the writing systems of the world, including most of constructed ones. Great site, very thorough, with sample sentences to boot.
"but probably not": Actually, probably so. The scholars who favor the indigenous explanation are a small minority outside of India. It's possible it was independent, but very, very doubtful, and none can explain the enormous gap in time between the Indus script and later Brahmic scripts.
What does it matter if some scholars are from outside of India? All I am seeing are conclusions from unstated assumptions that appear to be drawn from a bias.
My conclusions are coming directly from the Wikipedia articles that I linked to. If I am that wrong then edit the Wikipedia articles.
The Wikipedia articles say the majority of scholars believe it's based on Aramaic, while a minority of people (primarily non-linguistic-specialists in India) disagree. I think you're the one drawing from bias.
As they said in the comment you replied to: "Note that a sufficiently prompted AI agent can definitely read this, so it's not meant to be cryptographically sound, more just unfriendly to the common AI reader!"
