This tree was disregarding the low temperatures.
I ended up going in to work this morning for a few hours. I had to move around some boxes that had been delivered last night – very heavy so not something I wanted to ask Jan or Kim to do. They included new shipment of picture glass from our framing supplies vendor. I also ended up macgyvering a brand new vacuum cleaner that was (apparently) of quite low quality. I got it working, though.
