//! `s3m-core` — the reusable S3 client and streaming engine behind the `s3m`
//! CLI.
//!
//! This crate is intentionally free of any command-line concerns so it can be
//! embedded by other applications. The two top-level modules are:
//!
//! - [`s3`]: the S3 client ([`S3`]), credentials, region, signing, and the
//! typed request [`Error`](s3::Error) returned by every action.
//! - [`stream`]: resumable multipart uploads plus the compression/encryption
//! transfer pipelines.
// Curated re-exports: the core building blocks a consumer needs without
// reaching into deep module paths.
