# The producer Pico Pod hosted by the Manifold RuntimeEnvironment.
#
# This Pod plays the role of a Pico engine hosting the Pico Element
# "hello-producer-pico" in the Phase 7 vocabulary. It publishes exactly one
# event of EventType "hello.greeting" onto the Wrangler-declared Channel
# "greeting" and exits. The consumer Pico ("hello-consumer-pico") is
# subscribed to that same Channel and reacts by producing one Observation.
#
# The producer connects to the Channel via the in-cluster DNS name of the
# greeting Service ("greeting.manifold.svc.cluster.local:8080"), which
# resolves to the consumer Pod behind the Channel. Apply this manifest
# AFTER the consumer Pod is Ready so the connection succeeds.
