/* Totum Nexum — gedeelde basis uit het nieuwe ontwerp (totum-nexum-ontwerp).
   Bevat: tokens, header, mobiel menu, footer met themaschakelaar en de kleine
   componenten (knop, label, tag, kaart, terminalkaart).
   Laad dit bestand NA style.css: de tokens hieronder overschrijven de oude.
   Alles heeft het voorvoegsel tn-, zodat het niet botst met de oude opzet.
   Donker is standaard; licht komt via data-theme="light" op <html>. */
