Not sure this is sensible in 2023.

I'd suggest:

    font-family: system-ui, sans-serif;

After all, the purpose of system-ui [1] "is to allow web content to integrate with the look and feel of the native OS". Seems like a natural for something that's supposed to be minimalist.

system-ui [2] is supported by 96% of web users, so there's no reason not to use it.
