/* Geothermal REC Calculator page.
   Olive geothermal theme, matching the tokens used on the geothermal REC info
   pages (geothermal-hero.css) rather than the teal SREC palette.

   The step navigation itself comes from the shared css/form-stepper.css; this
   file only re-themes it through the --fstep-* tokens below. Square marks and
   a flatter treatment keep it visually distinct from the registration flow,
   which uses the same component with large round teal circles. */
