        Our goal is to fit sprites evenly in a row without leftover space.
        Flexbox's `space between` property gets us close, but doesn't flow
        well when the # of items per row > 1 and less than the max per row.

        Solving by explicitly calc'ing the width of each sprite. Setting
        `border-box` simplifies things, because content, padding and
        border-width all are included in the width, leaving us only to subtract
        the left + right margins.
