Let the header and footer follow the main column

With keep_columns and empty side columns the posts sit in a centred
column while the header and footer still run edge to edge, which reads as
two different pages stacked. The new switch insets their content by the
column widths (the backgrounds stay full width, phones are untouched) so
the whole page lines up as one column — the look a single-column site
expects, without bringing back a content max-width.
