/* =========================================================
   ORDTOGET — MOBIL
   Designprinsipper:
   - Alt som skal trykkes ligger nederst, i tommelsonen.
   - Skjermtastaturet er oppe nesten hele tiden. Layouten måles
     mot visualViewport, ikke mot vindushøyden.
   - Ett blikk skal holde: neste bokstav er det største elementet
     ved siden av toget.
   - Ingen hover. Trykkflater minst 48 px.
