style.scss file that combines a bunch of my ITCSS folders into the final CSS file:@use should always live at the highest lines in my file. components, there is usually a file called index.scss and some component files called _component-x.scss _component-y.scss. (These are just examples).@layer components within this structure. Should I define it at the component file level? Should it live in index.scss which gives me the same issue as in my style.scss. _component-{x}.scss in an @layer block. If that's what's needed I'll do it, but I'd like to know if there's a better way.
