1//! Data-only definitions for Chrome transport identity profiles.
2//!
3//! This module defines the configuration schemas used by the `tls` and `http2`
4//! modules to construct browser-identical network handshakes. No protocol
5//! logic resides here; these structures serve as the single source of truth
6//! for all fingerprint-sensitive parameters.
7//!
8//! Each [`ChromeProfile`] encodes a complete, multi-layer network identity
9//! spanning TLS (Layer 4), HTTP/2 (Layer 5), and HTTP metadata (Layer 7).
