pixelfed/pixelfed-rn — reverse-engineered prompt

Build me the official Pixelfed mobile app as a React Native app.

I want a clean Instagram style photo sharing app for Pixelfed and the fediverse. Users should be able to open the app, sign in to their Pixelfed account, browse a feed of photos, view posts, see profiles, and generally use Pixelfed from their phone in a polished way. It should feel native on both iPhone and Android, with a modern layout, good spacing, smooth navigation, and a nice image focused design.

Please set up the project so it can run with Expo and build for Android and iOS. Keep the code organized and ready for real app store builds. Use the existing Pixelfed branding and assets where appropriate, and follow the style of the official Pixelfed mobile app screenshot if you need a visual direction.

Look up current Pixelfed and React Native docs online if you need to.
