//! Compile and runtime tests for docs/library/providers/fiscaldata.md
//!
//! Requires the `fiscaldata` feature flag:
//!   cargo test --test doc_fiscaldata --features fiscaldata
//!   cargo test --test doc_fiscaldata --features fiscaldata -- --ignored   (network tests)
//!
//! Offline behaviour (series-id resolution, string-encoded numbers, the
//! `"null"` sentinel, pagination, API error mapping) is covered by the mock +
//! unit tests in `src/adapters/fiscaldata/mod.rs`.
