Prototype the Expert Talk Web and TUI experience #253

Question

Which Web and interactive TUI experience should represent Expert Talk?

Create one low-cost shared prototype that covers model-pair selection, role labels, cost disclosure, one-shot or persistent state, live stage progress, cancellation, partial failure, and the fused result. Test narrow Web layouts, keyboard use, screen-reader labels, and narrow terminal widths.

Resolve the accepted interaction model and record the prototype as a linked public asset. Do not implement production code.
