This is impressive -- Google sheets stalls out for me all the time with data sets that are pretty small, all things considered. What was your trick for making it so much faster inside the same browser? Anything design decision that stands out?

A couple of things that really help...

Matrices isn't editable (sort of by design) and works best for columns that are all of the same type. It then uses arrow for fast in-memory analytics.

Google sheets has to serve a much broader array of use cases, so I think they can only do so much to improve the performance. It can't always rely on having consistent rows and columns.
