from release v1.7: check if css modules will work in chunks/modules as desired

context: since we're cooking a heavily opinionated version of eruption to be served with the cli at install, we need to make sure that our bundling model of the lib version, would "simply work as desired" on the core "using the lib".

it's more specific and maybe makes sense when you look to something like new mantine v7, but it's the way we want to address it, so it need to be checked.

on tests made at #59 - and at our job - even tho we're using css modules, it doesn't do the chunks/module. it compiles a single css sheet. maybe investigate it with postCSS to see if it's something there with the bundle of vitejs.
