   1. LETTERTYPEN
   Voorkeur is zelf hosten (snelheid + privacy). Vanwege een netwerkbeperking
   in de bouwomgeving zijn de woff2-bestanden nu niet automatisch opgehaald;
   de site laadt de fonts daarom voorlopig via de Google Fonts CDN (zie
   enqueue in functions.php). Onderstaand blok staat klaar om te activeren
   zodra de woff2-bestanden in assets/fonts/ staan — zie README.md.
