# Render a promote manifest as a human-readable change-set for review.
#
# A manifest is a JSON array of operations using SYMBOLIC refs (@name) instead of
# ids, so the SAME manifest replays on sandbox or prod:
#   [ {"op":"thirdparty","ref":"tp1","input":{"name":"OVH","role":"supplier"}},
#     {"op":"invoice","ref":"inv1","input":{"socid":"@tp1","kind":"supplier",
#        "ref_supplier":"X","validate":true,"lines":[{"desc":"Hosting","qty":1,"price_ht":80,"tva":20,"type":"service"}]}},
#     {"op":"payment","input":{"invoice_id":"@inv1","mode":"VIR","account_id":1}} ]
