+- The mark at the head of the navigation column takes the column's full width
+ instead of the 110px it kept from the bar. In a row that size was all there
+ was room for; in a column it left the mark ending halfway across, with no
+ edge shared with anything below it. At the column's width its edges line up
+ with the page entries under it, as the full mark already does with the card
+ beneath it on the signed-out pages. Where the column lies back down into a
+ bar it returns to the compact size, which is what fits beside the entries.
