//! H2Settings source — Warm tier (B8).
//!
//! Computes an Akamai-style fingerprint from the h2 SETTINGS frame
//! parameters observed on the connection. Today the TargetContext
//! does not carry h2 SETTINGS data; the source is registered with
//! empty `analyze` so the slot is ready when B14 plumbs the frame
//! through.
