## Architecture

### Core Components

- **`org.codelibs.curl.Curl`**: Static entry point providing factory methods for all HTTP methods (GET, POST, PUT, DELETE, HEAD, OPTIONS, CONNECT, TRACE)
- **`org.codelibs.curl.CurlRequest`**: Fluent request builder supporting parameters, headers, body content, SSL config, proxies, timeouts, and caching
- **`org.codelibs.curl.CurlResponse`**: Response wrapper implementing `Closeable` for proper resource management
