/**
 * 上传/下载时的原始文件内容，覆盖浏览器与 Node 两端形态：
 * - Node 端：`Buffer`（属于 `Uint8Array`）、可读流（含 `size`/`byteLength` 的对象）
 * - 浏览器端：`Blob` / `File` / `ArrayBuffer` / TypedArray 等 `ArrayBufferView`
 * - 纯文本内容：`string`
 *
 * 末尾的 `{ size?: number; byteLength?: number }` 兼容自定义流对象（实现层据此推算
 * content-length）。这是一个开放联合：既约束常见形态，又不排除运行时特殊对象。
