   ORDTOGET — PC
   Designprinsipper:
   - Bredden er ressursen: lang skinnegang, mange vogner synlig
     samtidig, og togstallen alltid framme ved siden av.
   - Tastaturet er hovedinngangen. Snarveier vises, ikke gjemmes.
   - Musepeker finnes: hover og tooltip er lov.
   - Innholdet sentreres, men bruker skjermen.
