/* Discovery Energy — site styles
   Follows the Discovery Energy Web Page Design Standard v1.1 (.de-* system):
   Inter; lime #bfdd39 heroes and rules; ink #0d0d0d headings; green for actions;
   soft #f4f6ef alternating sections; square lime step badges; ink CTA band.
   Contrast notes from the standard are kept: white on --green-dark is 4.75:1,
   --green-text is 5.4:1 on white. Edit tokens in :root to restyle everything. */
