/* Certificaatgenerator — design tokens
   Concept: een officieel document, in software-vorm. Wit/grijsblauw als basis (het "papier"),
   één gedragen inktblauw voor interactie, en brons/zegel-goud als spaarzaam gebruikt accent op
   het merk-embleem. Labels en cijfers in monospace: het knipoogt naar serienummers op een
   certificaat zonder dat de site zelf gaat verkleden als perkament. */
