v1.3.0

Added

• Install Atlas as an app (PWA) — Atlas now installs to your phone's home
  screen and launches full-screen, without browser chrome. On Android use
  Chrome's "Install app"; on iPhone use Safari's Share → Add to Home Screen.
  Once installed, a service worker keeps the pages you've already opened
  viewable offline, so an itinerary loaded before takeoff is still there on the
  plane. Offline is read-only — adding or editing still needs a connection — and
  the trip-map basemap isn't cached, so the trip map shows a brief offline
  notice while its flight arcs, pins, and country shapes still render. See
  ADR-0017.
