/**
 * Request-body validation for the ui_request route.
 *
 * The handler validates with `parseBody`, so a malformed body is rejected with
 * a `BadRequestError` (→ 400) instead of the raw `ZodError` a bare `.parse()`
 * surfaces — which neither adapter maps, so it becomes a 500 — before any
 * interactive UI surface is requested.
 *
 * The handler is `async`, so the rejection surfaces as a rejected promise.
