Review the grid for article pages on the ipad

The grid for article on the ipad gets a bit convoluted at the end of the article. Review with Jos to explore options.

Review if these issues are still happening with updates to the mobile grid layout as well.

Start by reviewing the article-page grid and mobile grid layout against the attached iPad screenshot. Discuss the layout options with Jos and verify whether the reported issues still occur after current mobile-grid updates; done means the end-of-article grid works cleanly on iPad.
