Overview

A byte buffer that crosses the JS boundary as a ‘Uint8Array` (rather than a plain Array). Wrap a host method’s byte-array result in this so JS sees a real typed array — e.g. ‘TextEncoder#encode`, `Blob#arrayBuffer`. The reverse direction (a JS ArrayBuffer/TypedArray argument) arrives as a `Bytes` too. It subclasses Array so plain-Array callers (and `== [..]` comparisons) keep working; only the bridge treats it specially.
