## Overview

GitHub User Explorer is a browser-based React app for searching public GitHub accounts and exploring their profiles and repositories. The main workflow runs from username entry through SearchPage, parallel user and repository requests, then profile display and client-side repository filtering and sorting. App also routes to user-profile and repository-detail views. Search history and theme preferences persist in browser storage; a separate rate-limit request supplies status information. The README documents detail-view capabilities whose page implementations were not sampled, so their internal wiring is not inferred here.

Main entry points: [`src/pages/SearchPage.tsx`](https://github.com/amen-meb/githubuserexplorer/blob/main/src/pages/SearchPage.tsx) (Search page), [`src/App.tsx`](https://github.com/amen-meb/githubuserexplorer/blob/main/src/App.tsx) (App routes), [`src/components/SearchBar.tsx`](https://github.com/amen-meb/githubuserexplorer/blob/main/src/components/SearchBar.tsx) (Username search), [`src/hooks/useGitHubUser.ts`](https://github.com/amen-meb/githubuserexplorer/blob/main/src/hooks/useGitHubUser.ts) (User lookup)
