# Emit the effective config as a re-sourceable block, driven by CONFIG_SPECS
# (task mr0): the field set and their print order are the registry order, and
# each field's print_kind facet selects scalar (%s=%q) vs array (%s=( ... ))
# output. This replaces the hand-kept print list that had to stay in lockstep
# with apply_config_defaults. CONFIG_SOURCE is printed first and is NOT a
# registry entry: it is the resolved config path, not a config variable.
#
# The two array fields are not plain shell variables at print time -- they are
# normalised through resolve_tar_opts / resolve_sync_destinations (which fill an
# unset/empty array with its default) -- so the loop dispatches array fields to
# those resolved local copies rather than reading the raw global.
