/* Start screen (landing). Result first: the finished card and the hero motion lead, the two
   actions sit right under the headline. Only the landing entry uses it; invitation, camera
   preparation and the live views keep their own layouts. Colours come from the Habitus tokens, so
   the dark theme follows automatically; the example cards are printed artefacts and stay paper. */
