# Required GitHub repository secrets:
#   OMCSI_DEPLOY_URL   – Base URL of your omcsi instance,
#                        e.g. https://mc.example.com:8092
#   OMCSI_DEPLOY_TOKEN – The value set as DEPLOY_AUTH_TOKEN in your omcsi .env
#
# Required GitHub repository variables:
#   PLUGIN_JAR_NAME    – Filename of the plugin JAR on the server,
#                        e.g. ActivityTracker.jar  (the file that will be replaced)
