"""Reaction (tapback) tests for PhotonAdapter.

Outbound reactions go through the sidecar's ``/react`` / ``/unreact``
endpoints; these tests stub ``_sidecar_call`` to assert endpoint + body
shape. Inbound reaction events are fed straight to ``_dispatch_inbound``.
Neither path spawns the Node sidecar or binds ports.
