   Three colours: white, near-black and CIIS pink. Pink is only ever a background
   (the main button, the "Join CIIS" band, the dot of the open menu item), never
   text. Greys are black at an opacity. System type (San Francisco on Apple
   devices), Noto Sans Khmer for Khmer. Few icons: chevrons and the menu button.
