braze-sync 0.2.1

//! Raw configuration types deserialized from `braze-sync.config.yaml`.
//!
//! See IMPLEMENTATION.md §10. Every struct here uses
//! `#[serde(deny_unknown_fields)]` — the config file is the **only** place in
//! braze-sync where unknown fields are rejected. Resource files
//! (`schema.yaml`, `template.yaml`, etc.) stay forward-compat permissive
//! per §2.5.
