   KAI KARL — Samtgemeindebürgermeister Suderburg
   Static one-page campaign site. Design tokens translated from
   the source design system (tokens/colors.css, typography.css,
   spacing.css) and extended with fluid type, motion and a
   distinct poster-inspired hero built from the print flyer's
   own device: full-bleed blue field, bleeding cutout portrait,
   oversized wordmark, rotated tagline ribbon.
