   Lab report / measurement card look: warm paper, ink navy, one petrol blue; figures in IBM Plex Mono. The verdict
   colours (onder de richtwaarde green, erboven amber, onbekend grey) always come with a word, never colour alone.
   Unlike zwemwatercheck (teal waves), waterhardheidswijzer (system font, blue cards) and tijgermuggen (comic):
   ruled lines, a grid-paper hero, a left table of contents on text pages. */
