//! DefiLlama provider implementation (keyless).
//!
//! Serves the DeFi slice of `CRYPTO`. `fetch_crypto_quote` is the trait's
//! required primary operation, but DefiLlama publishes TVL rather than prices,
//! so it reports `NotSupported` and dispatch falls through to an exchange or
//! aggregator route.
