//! FINRA provider implementation (keyless).
//!
//! Serves the short-volume slice of `FUNDAMENTALS` only. `fetch_financials`
//! is the trait's required primary operation but FINRA publishes no financial
//! statements, so it reports `NotSupported` and dispatch falls through to the
//! next routed provider.
