  Ana Tamam — the site.

  The app's own surface rather than a website's: the cream page, the teal the
  splash opens on, the duck's yellow, and IBM Plex Sans Arabic, which is the
  face the app itself ships. A landing page in a different palette teaches the
  visitor the wrong thing about what they are about to install.
