They're referring to the font on the T-shirt.

Ah, I see. I’m sure the clothing designer that actually made the design couldn’t care less about technical consistency and was just looking for something ‘tech’ looking that also read well in that design context in that medium.

Thank you for spelling it out for me because I thought I was looking at a completely hallucinated AI article...

Author here. All hallucinations are my own. Now you point it out, I see why the jump in context from the terminal back to the tshirt font would give the wrong impression.

Honestly it was quite a whiplash to go from what looked like a good article to something that seemed completely made up. But I would chalk that up more to my reading comprehension than your writing.

I didn’t read it as generated text, but the context definitely threw me.
