+# Native question option preview
+
+`native-question-option-preview.android.ad` checks that every line of a long option preview is reachable on Android. Before replay, open a mock agent prompted with `emit synthetic questions` so its question card shows the first question, on a phone-sized emulator (validated on a 1080×1920 API 35 AVD). The flow opens the `rollout` question, drags slowly up from inside the "Behind feature flag" preview, and asserts the preview's last line is visible.
