I'm afraid I don't have the same analytic toolbox that you do, so I had no thoughts on them to this depth, thanks.
Something that did strike me is that, as a teenager on the other side of the iron curtain, I had been chasing girls at the local residential private school, who introduced me to anime — so the scene where Katya's friends are watching live-action japanese media seemed like a nice parallel (at least post-Glasnost) in our lives.
