//! USFM 66-book canonical table with HelloAO ID and locale name mapping.
//!
//! `canonical_id` is the USFM 3-letter book ID (`GEN`, `JHN`, `1CO`, …).
//! `helloao_id` matches what the upstream API returns under `book.id`.
//! `language` is ISO 639-3 of the surface language for the localized names
//! present in `aliases`.
