Binary Data Stream Processing using Reactive Uint8Array
Uint8Array typed arrays operate directly on raw ArrayBuffer memory. Utilizing shallowRef prevents Vue from attempting deep proxy wrapping on high-performance binary buffer structures.

Breakdown
1
const bufferStream = shallowRef(new Uint8Array(0));
Stores a TypedArray data type using shallowRef to track object reference replacement without proxy overhead.
2
const { value, done } = await streamReader.read();
Asynchronously awaits binary stream chunks from a ReadableStreamReader interface.
3
updated.set(bufferStream.value, 0);
Copies raw bytes from the previous Uint8Array buffer into the new binary buffer allocation.
