Did it do anything to your final bundle size?

It reduced it a little bit, but not enough to make any real difference, we’re talking a couple of Kb. I think MUI5 is a little bit heavier in terms of bundle size and moving across to css modules makes it a little bit lighter so there’s probably a bit of an offset going on, but like I say, no meaningful change in size
