/* Athenaion Journey
   Layout: the station picture fills the screen; a navy banner (like the city's own banners) names the
   station at the top left; round gold-rimmed "shield" buttons sit top right; Daphne speaks from a cloth
   strip along the bottom. Cards are marble tablets, postcards are paper, the map is parchment.
   One deliberate look in both themes: the picture is always the light source, the UI is cloth and stone. */
