   * this screen can skip itself — they already expressed their intent, no
   * reason to make them re-pick from the review footer. We `replace` (not
   * `push`) so Back from the destination goes to `community-save` instead of
   * bouncing through here again. The action is cleared synchronously via
   * `updateState` to guarantee the redirect only fires once: later visits to
   * `/create/review` (e.g. navigating here directly) render normally.
   *
   * Ref guard covers React 18 StrictMode's double-mount in dev so we don't
   * fire `router.replace` twice on the same transition.
