 * Supported shapes (receivers should accept all of these):
 * - **String `data`:** preferred wire form (`createTransferAssetStreamChunk` / `encoding: 'base64'`).
 * - **`{ type: 'Buffer', data: number[] | TypedArray }`:** legacy `Buffer.toJSON()` from default
 *   `JSON.stringify` (older clients/servers).
 * - **`Buffer` instance:** in-process only.
 *
 * Note: Node’s `JSON.stringify` runs `Buffer.toJSON()` before any replacer, so nested `Buffer`
 * values become the legacy object unless you pass a string (use `createTransferAssetStreamChunk`).
