yes, at first it would run simulator tests on all font sizes but it stopped after I asked it not to do that until UI review
maybe sol would have done the same thing, idk. but I find the whole process to be really nice with astra. I use it on high unless it says something is impossible then i go max and ask it to find alternatives (happened once)
If a person, or team of people, can build a demo quickly then it's good odds that they can build the real version (though, famously, not a guarantee). However, it turns out that a machine that can spit out 100 demos of whatever can't actually build the real thing.
Similarly, a chess engine rated to 1000 Elo doesn't play like a 1000 rated human being. The mistakes that each make to reach the equivalent level are different in size, frequency and kind. The thing that makes a human reach a good demo is very close to the skillset to reach the finished article. This isn't so for LLMs but we have yet to update our priors.
