// The built-in network configs in this file are the canonical sources used by
// backfill when persisted or custom configs omit fields that should inherit a
// known network default. BackfillMissingFieldsFrom copies generic fork blocks,
// system-contract addresses, consensus-engine stubs, and nested XDPoS defaults
// from these presets into the destination config; BackfillCustomMigratedFieldsFrom
// reads the same presets only for the narrow historical custom-migration
// whitelist. Keeping these presets complete and explicit defines what later
// backfill is allowed to inherit.
