Dropped 32 points last hour, happy about that. The main thing is the insight that mors is not called for right after vitae, and thus it doesn't need to be accessible from bonder.

I probably could spend more time here if I started area earlier to see how regular backward build is. In sum, building a polymer exactly isn't usually huge - you pay about 0.8R in cycles and a simpler build sequence can be worth that. But here the chain is so sparse you also shave about 10 area on top of cycles.
