/* Tur Kasası sunumu — one screen, one route. The route pans one stop gap per step while panels swap in place,
   so the line, the minibus and the content move as one scene. Visual-first: one headline, one picture per stop;
   details live on the last stop. Light only, by choice: a printed route map. */
