# WordPress Multisite opt-in.
#
# Runs only when `services.wordpress.multisite.enabled` is true.
# Converts the fresh Single-Site installation into a sub-domain Multisite
# network and creates one site per canonical domain beyond the first.
# Domain mapping is handled natively by WordPress core since 4.5.
#
# Idempotent: if the network is already enabled, `wp core multisite-convert`
# prints an informative message and exits 1 - we ignore that so re-runs
# stay green. Sites that already exist are detected via `wp site list`
# before `wp site create` runs.
