CSS grid-pad's wildcard matcher removed - grids within grids had padding bugs.
CSS Grid removed  grid-pad around the article and aside. Instead centering using page-wrapper.
CSS Grid removed last-of-type matcher and added padding-right 0 by hand. The last of type
         was probably meant to only support single rows nested within a grid wrapper.
         There were interactions with grids within grids with the wildcard matcher.
         Frankly, at this point, I didn't trust the solution and wanted to simplify.
CSS Grid changed from clearfix -> pie-clearfix. clearfix was removing the box-shadow over the
    gutter. A standard clearfix solution didn't and the pie-clearfix didn't. So switched.
    Didn't even seem to be related to margin or padding.
