//! Compile and runtime tests for docs/library/providers/bls.md
//!
//! Requires the `bls` feature flag:
//!   cargo test --test doc_bls --features bls
//!   cargo test --test doc_bls --features bls -- --ignored   (network tests)
//!
//! Offline behaviour (period-code dating, the `"-"` sentinel, annual-aggregate
//! rows, tier selection, error mapping) is covered by the mock + unit tests in
//! `src/adapters/bls/mod.rs`.
