/* ==========================================================================
   KIPPRA Recruitment Aptitude Test — visual identity (v2, simplified)

   Design intent: read as solid, trustworthy institutional software, not a
   design showcase. One primary color (KIPPRA green), one typeface, minimal
   ornamentation. Restraint is the point — professional software earns trust
   by being clean and predictable, not by being visually "interesting".
