/* Tipping points page (js/views/tipping.js). Owner: the alerts module agent.

   table.data, .m-D/.m-R) and variables come from app.css. The three sources are drawn in colours that are NOT party colours
   (violet = pre-election forecast, cyan = prediction markets, white = the live needle) so a line is never mistaken for a side. */
