/*
  Oefenpagina Distelhof Interieur.

  Alles buiten de drie gemarkeerde fouten is bewust wél in orde: zichtbare
  focusring, voldoende contrast, leesbare regellengte, koppen op volgorde.
  Eén pagina met drie herkenbare fouten maakt de demo scherp; een pagina die
  overal rammelt maakt hem juist vaag, want dan is niets meer het punt.
