I suspect it is not using browser font rendering. That puts it effectively back into Windows 3.1 days of bitblt graphics, being driven by a difficult to optimize, dynamic language. It is indeed wild that desktops are good enough to be able to drive such a thing with such performance. However, there is plenty of reason to rely on native frameworks with modern graphics systems. I suspect there were radically different levels of engineering and optimization that went into Google Sheets vs a typical pizza-ordering app. Even with the same level of engineering, I suspect the pizza ordering app would be larger due to the need to bundle media like pizza and topping images.
