# Zones to include in catalog zones
#
# Format:  <zone>  <catalog>[, <catalog>...]  [, group=<value>]  [, coo=<fqdn>]
#
# - Catalogs are bare names matching keys in catz.yaml
# - group: RFC 9432 property — consumers apply shared config to grouped zones
# - coo:   RFC 9432 change-of-ownership — points to the old catalog during migration

# Simple: zone in one catalog
app.example.com          prod

# Zone served by multiple catalogs
example.com              prod, staging

# Group property — lets consumers apply per-group policy
api.example.com          prod, group=critical
dev.example.net          staging, group=testing

# Change-of-ownership — zone migrating from another catalog
legacy.example.org       prod, coo=old-catalog.example.com.

# Both properties
internal.example.org     prod, group=internal, coo=old-catalog.example.com.
