/* ============================================================
   PHONE
   Not the desktop layout scaled down. The desktop page is a wide
   two-column read: a chart pinned on the left, its story scrolling
   past on the right. Folded onto one column that becomes a chart
   sitting *on top of* its own story, and the two fight over the
   same 844 pixels. So on a phone:
     · the pinned block carries the chart and nothing else
     · the search moves up out of it, into the section head
     · the caption shortens to one line that the story doesn't
       already say, and stays with the chart
     · the lens bar becomes a rail that fits, instead of a
       sideways scroller cut off at the edge
     · every row chart puts its label on its own line and gives
       the track the full width
