 * rejected early via `endResponse`. Bodies are also counted while streaming (via
 * `TransformStream`), including when `Content-Length` is missing, wrong, or overridden — so a
 * short `Content-Length` cannot bypass the limit. `Transfer-Encoding` and `Content-Encoding`
 * cases are covered by the same byte counter.
 *
 * When using `useContentEncoding`, register it **before** this plugin so the byte counter sees
 * decoded bytes. `onRequest` hooks run in `plugins` array order; the reverse order would count
 * compressed size and then allow decompression past `limit`.
 *
 * To disable limiting, omit this plugin from the adapter.
