/* Thematische kleurplaten

   Er staat maar één laag op het papier: de SVG van de plaat. De tekenvolgorde
   is de DOM-volgorde (vakken -> verf -> contouren -> kleurwijzer), dus hier
   staat geen z-index-stapel en geen mix-blend-mode meer. Belangrijk: dit
   bestand zet nooit een `fill` op een kleurvak - dat zou van de vulling van de
   verfemmer winnen en de verf onzichtbaar maken. */

   teach.css) zodat ze niet permanent ruimte innemen. */
