/* Interior X, de landingspagina.
   Acht kleuren uit stuk 5, geen negende. Groen is klaar, rood is open of escalatie,
   amber vraagt om een handeling.

   De pagina loopt van rand tot rand: er is geen kader met een vaste breedte. Alle maten staan in rem
   en de basismaat groeit boven 1440 pixels mee met het scherm, zodat een breed scherm een groter
   beeld krijgt en geen lege stroken. Alleen lopende tekst houdt een regellengte. */
