Before I even talk about the poem, I'd like to say that your leadup was pristine. The context, the terminology, it's great. Makes it feel very real, very in-universe. Onto the poem: I like the rhythm. I like a good deal of the lines. I get the footnotes, I understand the idea behind the alternate language, but in all honesty, it takes away the flow. Which was unsatisfying. Stumbling over a word, and then taking yourself out of the rhythm by reading an explanatory footnote, makes this cease to be read as a poem, if you catch what I mean.
Besides that, I like all the vibes here. The CSS is an easy way to predispose me to like the article, and the article doubles down on that vibe and really sells it. I like Fifthist stuff nearly on principle, so you got me there, and then you did some genuinely tight and interesting worldbuilding, which is always a plus. So, you hit the mark again and again, and that's what upvotes are all about babyyyy! +1
