> The federal government has a very good design system.
Having no knowledge of how the federal government works, but having worked for fairly large organizations, I would still guess that the design system exists and is used in many places but a significant fraction may not even know it exists much less that they are supposed to use it.
Seconded. Plus many Fed'Gov orgs have explicitly different systems, requirements, and silos. The DOD or NSA would put out something flashy, but this is State...
Not "the government." "A person in the government."
The federal government has a very good design system. But for some reason, whoever built this page chose not to follow it.
