/* De kop van de site (partials/kop-nieuw.pug).
   Alle kleuren via de --kop-…-variabelen hieronder. Licht en donker zetten
   --card-bg, --primary-color enz., maar blauw, groen en roze niet: die
   hebben eigen namen (--secondary-400) en kleurden de oude .header met eigen
   regels. Zonder dit blok bleef de kop daar standaardblauw (2026-10-28).

   Breedtes:
   - vanaf 1100px: alles in één balk
   - 900–1100px: menu naar het paneel, knoppen blijven in de balk
   - onder 900px: alleen logo, cadeau-icoon, account en de menuknop
   - onder 480px: merknaam kleiner, cadeau alleen als icoon */
