Illustration > Add XS grid size
Purpose
A new extra small (XS) grid is being added to provide a size that illustration elements can be created at when they're used alongside other UI or to comprise part of a larger design.
For example, in gitlab-org/gitlab-svgs!794 (merged) a "bidirectional-xs" illustration is being added to connect two logos. Because of our third-party trademark policy we didn't want to add this to one of the logos or combine them. The 72px grid here would've been too large in relation to the logos and placed emphasis in the wrong place.
36px was chosen instead of 32px (and base 8) in order to follow the illustration pattern where each size increases at 2x.
