/* IT HAS TO SCROLL, AND IT HAS TO FILL THE PANE.

   This was a fixed-width block with no height and no overflow, dropped into
   .rview - which is a flex column with overflow:hidden. So anything past the
   fold was clipped and unreachable (Ethan: "stuff down below the page that is
   cut and cropped out of scene"), and the block itself sat as a narrow strip
   at the top of a wide pane rather than looking like a screen ("why is it
   just some weird little thing sitting there").

   flex:1 + min-height:0 + overflow-y makes it the scrolling body of the pane,
   and the gutter is --doc-col so it lines up with every other screen. */
