(Or, I don't think we're actually saying this but, e.g...)

Do we actually want to say the Stanford theme for spotlight sites should set: `$padding-large-vertical: 20px`, and that this is just `$padding-large-vertical`.

I agree we shouldn't compromise on visual design, especially for our sites, but by using standard bootstrap variables, we (hopefully) make it easier for others to tweak bootstrap styles globally and don't need to care about spotlight-specific styles.
