/* Kodza — Stat Card
   A key figure, its change and the curve that led there. When the card comes into view the
   figure rolls into place, the curve draws itself and its area rises; point at the curve and
   a guide follows you, telling the value of the day. The trend (data-trend: up, down, flat)
   is said by an arrow, never by a color. The curve comes from data-points (and data-labels).
   Everything is tuned with the --kz-stat-* variables. */

// The script changes this markup once React has rendered it (it adds layers, splits text, moves
// nodes), so React must not patch it afterwards. When a prop changes, the key gives React a fresh
// element: kodza:destroy stops the script on the old one, kodza:init starts it on the new one.
