## Architecture

### Core Components

- **`Curl`**: Static entry point providing factory methods for all HTTP methods (GET, POST, PUT, DELETE, HEAD, OPTIONS, CONNECT, TRACE). Also defines the `Method` enum and `tmpDir` constant.

- **`CurlRequest`**: Fluent request builder supporting query parameters, headers, body content, GZIP compression, SSL configuration, proxy settings, encoding, threshold, custom connection configuration, and async execution.
