This doesn't follow at all - architects are much more aware of standards than you are implying. They are not just clueless artists saying "please make it look like this". It's insulting to compare them to vibe-coders.
Unrelated: The phrase is "flesh out". You "flush out" unwanted elements, like rodents.
The analogy, not the 1 to 1 translation, is that the architects come up with the ideas and pass them off to the workers to implement.
