Purpose: Safe, conservative default values for every configuration schema — the baseline every environment/tenant inherits from unless it explicitly overrides.
What belongs here: One *.default.yaml file per schema in config/schemas/, validating against it.
What must not be stored here: Tenant-specific or environment-specific values (→ config/tenants/, config/environments/), secrets.
