   Doel: Globale UI-styling & utilities
   -----------------------------------------------------
   - Bevat basisopmaak voor knoppen, navigatie, formulieren
   - Bevat kleine utilities die overal bruikbaar zijn:
     * .skip-link          toegankelijkheidslink, alleen zichtbaar bij focus
     * .visually-hidden    alleen zichtbaar voor screenreaders
     * .clearfix           clearfix voor floats
     * .text-center/left/right  tekst uitlijning
     * .mt-/.mb-/.p-*    kleine spacing-helpers
   -----------------------------------------------------
   Richtlijn:
   - Alleen herbruikbare en globale UI-componenten.
   - Pagina-specifieke styling hoort in /css/pages/...
