/**
 * Provides the service used to run outgoing HTTP requests.
 *
 * `HttpClient` executes immutable `HttpClientRequest` values and returns
 * `HttpClientResponse` values. Keeping HTTP behind this service lets programs,
 * tests, and generated API clients use the same request model without depending
 * on one concrete platform transport. This module includes request accessors,
 * constructors and layers, request and response transformations, status
 * filtering, retries, rate limiting, cookies, redirect handling, scoped request
 * abortion, and tracing support.
