/* ExamVerdict design system.
   The look comes from the paper answer sheet: form-green rules on white, graphite pencil marks,
   a pencil-yellow button. Shape rule: ovals are things you mark or press; square-cornered
   boxes are printed facts. The bottom-right corner of every page stays empty for the rank badge. */
