Say I have a config folder containing partials such as variables, mixins, functions, or just any partial that doesn't output it's own styles —the folder is copied to dist even though it will contain no compiled css

Sometimes we want to chain a class selector with itself for a low-risk specificity increase. Why?
Details here: https://csswizardry.com/2014/07/hacks-for-dealing-with-specificity/#safely-increasing-specificity

eg
This scss:

.social__icon.social__icon { // require specificity to override
	// stuff
}

results in this css:

.social__icon {
	// stuff
}

So right now the chaining gets removed and we end up with a single low specify single class. Weird! Not sure why these are getting flattened, might be part of minification? Needs investigation

If I add a new scss partial, the watch task ignores it until I modify a pre-existing file
