Liminal 1.2 for Linux x64

Run:
  ./run-liminal.sh

Liminal uses the hosted Liminality backend at https://liminality.physea.ai and
opens https://liminal.physea.ai when the optional local Physea service is absent.
Sign in with your Liminality API key. The key is exchanged for an HttpOnly
session cookie and is not stored by the application.
