"""
An invitation waiting on the home page, answered in the real application.
Being added to a group is an invitation until it is accepted (AV33). What only
the running application shows is that the home page lists it, that Accept and
Decline reach the hub, and that an accepted group then appears among the
reader's groups — while a declined one does not.
Loads the shipped `app.js` with `fetch` stubbed, once per case:
accept — the invitation is listed, Accept is clicked
decline — the invitation is listed, Decline is clicked
invitation_probe.py [--engine chrome|firefox]
Prints JSON: one object per case.
