# Send notifications to Basecamp Campfire via chatbot
#
# Two destinations, so release traffic does not drown the repository chat:
#
#   OMARCHY_RELEASE_CHATBOT_URL  release activity (starts, publishes, failures)
#   BASECAMP_CHATBOT_URL         everything else, and the fallback when the
#                                release URL is unset
#
# Each is the full chatbot lines URL from Basecamp, e.g.
#   https://3.basecamp.com/<account>/integrations/<key>/buckets/<project>/chats/<chat>/lines
#
# With neither set, notifications are silently skipped.
