There are Javascript frameworks and CSS frameworks. Tailwind is the later one. Even the Tailwind front page describes it as a CSS framework.

That’s technically true, but anyone I know in the field would immediately understand what is meant by framework agnostic in this case. Unless we’re being pedantic for the sake of it, of course.

Yes. I immediately knew what it meant. GP is being needlessly literal. Language is a communication tool. I, as the audience, was communicated to as intended. I’m not sure what this pedantry does for anyone.

by that logic nothing is a framework, everything "compiles" to js and css

I didn't say it wasn't a framework because it compiles. I would expect framework to be a large shift in how you write or structure code. But there's no agreed definition.
