Create an Android app called “Sequence” for young creators to turn photo sequences into short animated stories. Users pick photos from their device, drag to reorder, set a duration per frame, and add simple text overlays. They can preview the story and export it as an animated GIF or a short MP4. The interface should feel clean and minimalist, built in Jetpack Compose, with rounded photo thumbnails and a subtle gradient highlight for selected/active items. Save drafts and export preferences locally with DataStore. The app must be fully localized (zh-CN and ru-RU) and implemented in Kotlin. Ensure the project builds reliably with a Gradle wrapper and include basic tests or checks.
