My general sentiment regarding this is: Is it really necessary to add all the bootstrap stuff here? Could we just choose sensible defaults for the styles in the vellum repo and then override what we want to be consistent / fancy in the HQ styles?

Also, there isn't a lot of explicitness about what is being used here.
```
@import "bootstrap/variables"
@import "bootstrap/mixins"
```
makes me wonder what is being used from bootstrap, but there's no way to find out without looking through all of the vellum less files.  It would be nice to either (a) add a comment here that lists all the mixins/variables being used, so if someone decides to start using a new one, they have to think about whether it's something they should use here or maybe override in HQ styles instead, or (b) don't make it look like you're using all of the bootstrap variables and mixins by copying them all; just make a file with only what you're using and add comments saying that they came from bootstrap.

Plus, I could be wrong, but if you want visual consistency between HQ and vellum then what's the point of using, say, `@navbarBackground` from bootstrap/variables in these files, when you really want that variable from the HQ less files, and if you change it there you would have to change it here?  This speaks to the benefit of keeping vellum styles minimal and overriding stuff in HQ instead.
