"""Emit the email-template catalog as a pack-owned reference-data source
(deployments/offline/runtime/reference-data/email-template-catalog.json) so it
seeds to BOTH sandbox and PRODUCTION via the governed apply_pack_reference_data
path (manifest.json), not just the sandbox baseline seed.

Source of truth = migrated/*.records.json (regenerate via build_template_catalog.py).
The governed Account approval set (Account_Approved / Account_Rejected /
Account_Submitted_For_Approval_Notice / Account_Recalled + the
Account_Email_Templates folder) is owned separately by approval-email-templates.json;
this file therefore EXCLUDES folder_account_email_templates to avoid a duplicate
reference-data key. The catalog's Account templates still reference that folder
cross-file (the applier collects all sources into one record context).
