jellyfin/jellyfin-ios ? reverse-engineered prompt

Build me a Jellyfin iPhone and iPad app that lets people connect to their Jellyfin server, browse their media library, search for movies, shows, and music, and play content smoothly on iOS.

I want it to feel like a real mobile app, not just a website in a shell, but it can use Expo and React Native with a few native iOS touches where needed. Make the main flow simple, sign in, pick a server, see home and library screens, open details for a title, and start playback with basic player controls. It should support translated text too, since this app is used in different languages.

Please set it up so I can run it locally with the usual install and start commands, and make sure the project is organized clearly enough that I can continue adding features later. If you need current docs or platform details, look them up online first.
