  ✔ Demo space "The Commons" is live.

  Local URL:     http://127.0.0.1:$PORT/
  Admin:         http://127.0.0.1:$PORT/admin#token=$ADMIN
  Web check:     ./tools/dev shots web-check shot.png   (headless 2x screenshot)

  Sign-in link (localhost — one-time, signs you in as "Cass"):
    $LINK

  For the NATIVE apps use the tunnel instead (real https):
    In another terminal:  ./tools/dev shots tunnel
    It prints https://try-*.11relay.com links to open in the Mac app + on the iPhone.

  Ctrl-C stops the server.
