/**
 * /plan-design-review with UI scope (gate, paid, real-PTY).
 *
 * The exact UI-heavy plan is committed before the first model turn. Observe
 * an acknowledged Design focus/rating question and a subsequent review
 * question using the existing native counting driver. An initial target menu
 * or a no-UI early exit cannot satisfy this positive path. Option descriptions
 * are proposals, so mentioning "no UI scope" there is not an exit verdict.
