Write each preview as a standalone HTML file under preview/ in the project.\n- Scope: the Today list and the tide detail it opens. You may edit and add Swift files under Etale/ and write previews under preview/; create nothing outside the project. Etale/ is a folder the Xcode project keeps in sync with the disk: a Swift file added there is compiled, so do not edit Etale.xcodeproj.\n- The app targets iOS 26 and is built with Xcode 27. Xcode cannot run in this session: do not try to build. There is no network: install nothing.\n\nFinish with the final report the pipeline asks for.",

Leaving the push loses the edge-swipe back, the bar and its back button, the VoiceOver escape gesture and the navigation path.
