# workflow_vars.yml
# Exercises workflow:rules:variables: injection.
# The matching workflow rule sets DEPLOY_TARGET; job rules use it.
#
# Expected behaviour per context:
#   --branch main             → only build active (no workflow rule matches; WORKFLOW var not set)
#   --branch develop          → deploy-staging active, deploy-prod skipped
#   --branch feat/x           → only build active (when: always fallback, no deploy vars)
#   --var WORKFLOW=gitflow --branch us/feature → deploy-prod + build active
