Structured Clone Transfer Detachment Narration

Inputs: [JavaScript runtime], [small ArrayBuffer fixture], [intended ownership]. Contrast structuredClone(buffer) with structuredClone(buffer,{transfer:[buffer]}). In a supported runtime, show that copying preserves the source while transferring detaches the source buffer. Use only disposable fixtures; never transfer application data during diagnosis. Do not imply every object is transferable. Produce a 45-second explanation naming the source byteLength before and after transfer. Adapt the presentation to [audience] and [tone]. Check the defining task detail against the inputs before finishing.

Use only the supplied facts and approved wording. If a necessary script or timing reference is missing, ask for it first. Produce the audio when supported; otherwise return the complete spoken script with pauses and a short production cue sheet, clearly labeled as a script. Use original voices and keep speech intelligible without music. Never claim an audio file exists unless it was generated.
