This file exists because I don't know how to use rollup properly, I guess.

rollup-plugin-svelte in combination with rollup-plugin-scss (as a separate plugin, not in preprocessor) is emitting its stylesheets to a virtual file
presumably that file gets read by rollup-plugin-scss (or rollup-plugin-postcss, which is used as processor there) as stdin instead of global.scss, putting it into the sourceMap

(All of that is guesswork, I don't really know what's going on)

If you can help me figure out how to fix it, please help me.
