Yes, you got it, Fischer-Yates shuffle via lodash. Here's their implementation: https://github.com/lodash/lodash/blob/master/shuffle.js

Trying to work out how many bits the seed has, but it depends on the browsers implementation of Math.random() - in theory could be anything but apparently its usually Xorshift128+, which as far as I can tell has a 128 bit seed. So all good? Although I'm not sure where the 128 bits for the seed come from.
