The words social democracy and democratic socialism have swapped definitions and started the same and have been translated variously. It’s even more confusing than the word histories of socialism and communism.

My understanding of social democracy in the contemporary meaning is liberal capitalist society with substantial concessions to the working class for quality of life, while democratic socialism is a movement to end liberal capitalism via the ballot box.

Not that I am aware of.

Yes and also no. Yes because that is clearly the role it plays in the US. But no in the sense that it is a name for a specific theory of action, the theory that you can achieve socialism through voting instead of through a coup (even a bloodless one) or a civil/revolutionary war.
