   Mattenburghoeve – stylesheet
   --------------------------------------------------------------------------
   Opbouw:
   1. Design tokens (kleuren, typografie, maten) – pas hier centraal aan
   2. Basis (reset, typografie, links)
   3. Layout-hulpmiddelen (.container, .section, .prose)
   4. Componenten: skip-link, header/navigatie, hero, kaarten,
      fotorij, figuur, knop, contactblok, footer
   5. Responsive uitbreidingen (mobile-first: alleen min-width queries)
