/* ==========================================================================
   style.css — Design tokens + candidate-facing pages
   (index.html, assessment.html, result.html)

   Design direction: corporate recruitment tool that should feel like a
   modern online exam, not a marketing page. Cool, restrained palette;
   a grotesk display face paired with a workhorse body face; a monospace
   face reserved for anything numeric/data (assessment IDs, scores,
   dates) so those read as measured facts rather than prose.
