For me, it was this part of the paragraph:

> There is no atlas, so a hundred thousand CJK glyphs cost a font's worth of outline data, not an atlas the size of a video. Text can change every frame at no baking cost, which is exactly what you want for live data, user input, and localized content. And it all happens in a single draw with an ordinary fragment shader, no vendor extension required.

Specifically, these sentence structures:

1. ... so <blah> costs <blah>, not <blah>.

2. And <blah>, no <blah>.

3. ... fixed resolution ahead of time, which quietly ...

Stuff like this is a giveaway for me:

> Drawing it on a GPU, crisply, at any size, under any 3D transform, while the text changes every frame, is not.

> One small texture, resolution independent within reason, one cheap shader.

English is not my native language, so I may be wrong here.

For me it was "head to head" table. Typical complete nonsense llm-generated comparison table. Rest of the content is still quite good tbh, generated or not

I think it's a mix of human and LLM writing.
