micio86dev/nuxt-todo-app — reverse-engineered prompt

Build me a responsive todo app in Nuxt 4 with strict TypeScript. I want a clean, simple interface where I can add tasks, edit them, mark them done or not done, delete them, and keep everything saved in local browser storage so my list is still there when I come back.

Please make it feel good on both mobile and desktop, and keep the saved data client side so it does not cause issues with SSR. I want the app structure to stay clean, with one central store for the todo state and composables as the way components interact with it, instead of putting storage logic directly in the UI. If the saved data is broken or malformed, it should safely fall back to an empty default state instead of crashing.

Include the basic filtering flow for todos if that matches the project. Also add unit tests for the store and composables, and make sure the app can run, build, type check, and test cleanly. Look up current docs online if you need to.
