Structured Clone Transfer Detachment Visual

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 two-panel buffer ownership diagram distinguishing a copy from a detached source. Adapt the presentation to [audience] and [tone]. Check the defining task detail against the inputs before finishing.

Use the attached references only for the specified visual attributes. If a required reference is missing, request it before generation. Produce one finished image with a deliberate focal point, consistent geometry and clean margins. Keep any exact wording on a separate editable label layer or leave its area blank. Do not invent evidence or present an illustration as documentary proof.
