   Map controls, stations and walk lines (BUY-025)
   The style and station buttons sit at the top left below the floating
   header, the legend at the bottom left above the zoom buttons; both are
   Leaflet controls, so Leaflet stacks them with its own. Colours come from
   the theme variables, so the three themes need nothing of their own.
