//! Shared HTTP client for AWS operations.
//!
//! This module provides a singleton HTTP client with connection pooling for
//! efficient reuse across multiple S3 operations.

/// Returns a reference to the shared HTTP client.
///
/// The client is lazily initialized on first use and reused for all subsequent
/// requests. On native targets, it is configured with connection pooling for
/// improved performance when making multiple requests to the same host.
