/* Lorenz-96 chaos & predictability — embedding stylesheet.
   Scoped to .da-widget (same convention as the other tutorial widgets):
   the widget can be dropped into any page without touching page styles.
   Custom properties live on the .da-widget wrapper and inherit down.

   Series colors: truth = ink, ensemble members = aqua, error = red,
   spread = amber (matches the other widgets' palette vocabulary).
