   WOOD BUTTON SHADOW SYSTEM
   ---------------------------------------------------------
   Doel:
   - Simuleert een 3D houten knop
   - Inset shadows vormen afgeronde randen + houtvolume
   - Outer shadows geven gewicht en contact met de pagina
   - Hover = lichter + iets omhoog
   - Active = ingedrukt, compacter
