/* QM Vloerverwarming - eigen stylesheet, geen framework.

   Kleur komt uit het merk en uit het vak, niet uit een sjabloon:
   - het zwart van het logo en van de belettering op de bus
   - beton- en dekvloergrijs als rustvlak
   - een accent: het rood van de aanvoerzijde op elke verdeler
   Alle hoeken scherp (radius 0), een accentkleur, een lettertype. */
