   CENTIEM — Stylesheet
   Richting: het groene grootboek. Grootboekgroen als structuur, papiergrijze
   ondergrond, mono-cijfers voor alles wat geld is, statussen als rubberen
   stempels. Diepte via lijnen, niet via schaduwen.
   Fonts: Archivo (tekst en koppen) + Spline Sans Mono (bedragen, nummers).
