/* Domain credit under each major chart, so a screenshot shared on its own
   still says where it came from. Add class="chart-wm" to the element that
   wraps the chart. The label sits in an 18px strip of bottom padding, never
   on the drawing itself: a corner overlay collided with legends, titles and
   column headers on a dozen charts at phone width. Tooltips on the labelled
   charts are either position:fixed or already measured against this same
   wrapper, so making it the positioning box moves nothing. */
