   HOE DIT BESTAND IS GEORGANISEERD
   1.  Design tokens     — alle kleuren, fonts, spacing als variabelen
   2.  Reset & base      — browser-styling neutraliseren
   3.  Cursor morph      — cursor wordt ring op interactieve elementen
   4.  Scroll progress   — dunne balk bovenaan
   5.  Container         — centrale max-breedte
   6.  Navigation        — bovenste balk met liquid glass
   7.  Typography        — body, kops, paragrafen
   8.  Motion            — reveal animaties bij scroll-in
   9.  Sections          — homepage secties
   10. Footer
   11. Case detail hero
   12. Case blocks
   13. Client & Problem
   14. Process
   15. Impact

   GOUDEN REGEL
   Wijzig kleuren en spacing in sectie 1 (Design tokens), niet ergens
   anders. Eén wijziging daar propageert door de hele site.

   1. DESIGN TOKENS
   ================================================================
   
   Custom properties (CSS-variabelen) die overal in de site gebruikt
   worden. Wijzig hier en het effect is overal zichtbaar.
   
   Onderverdeeld in:
   - Spacing scale (8pt grid: 4, 8, 12, 16, 20, 24, 32, 40, 48, 64, 80, 96, 128)
   - Reading rules (kolombreedtes voor leesbaarheid)
   - Shape (border-radius)
   - Typography (font-families, sizes, line-heights)
   - Color tokens (light en dark mode)
   - Motion tokens (animatie-snelheden en easing)
