 ## Project Overview
 
-**InstaArchive** is a high-performance, React-based Progressive Web App (PWA) designed to browse and explore archived Instagram data with a native-feeling interface. It allows users to load their local Instagram archive directories (either official Instagram exports or Instaloader format) and browse posts, reels, and stories in a modern, responsive grid view.

+### Key Technical Features
 - **Local Archive Loading:** Uses the `webkitdirectory` API to scan and process local files securely on the client-side.
 - **Support for Multiple Formats:** Recognizes official Instagram export structures and Instaloader regex-based naming conventions.
-- **Dynamic Media Grid:** Customizable grid layouts (1:1 and 3:4 aspect ratios) with adjustable offsets ("bumps") for aesthetic alignment.
+- **Compressed Metadata**: Support for `.json.xz` file decompression using `xz-decompress` (WASM-powered).
-- **Story Viewer:** Native-like story experience with progress bars, automated playback, and touch/click navigation.
+- **Dynamic Media Grid**: Customizable grid layouts (1:1 and 3:4 aspect ratios) with adjustable offsets ("bumps") for aesthetic alignment.
-- **Post Detail Modal:** Comprehensive view for posts with media carousels, captions, and seamless navigation between posts.
+- **Story Viewer**: Native-like story experience with segmented progress bars, automated playback, audio controls, and chronological sorting.
-- **Video Support:** Automatic video thumbnail generation and playback.
+- **Auto-Unmute**: Videos default to unmuted when opened in full view for a better user experience.
-- **PWA Ready:** Built with `vite-plugin-pwa` for offline capabilities and a standalone application experience.

+## Commands
-
-## Building and Running
-
-### Prerequisites
-- Node.js (Latest LTS recommended)
-- npm or yarn
-
-### Commands
 - `npm install`: Install project dependencies.
 - `npm run dev`: Start the local development server on port 3000.
 - `npm run build`: Generate the production-ready build in the `dist` folder.
 - `npm run preview`: Locally preview the production build.
 - `npm run lint`: Execute TypeScript type-checking (`tsc --noEmit`).
-- `npm run clean`: Remove the `dist` directory.
-
-### Environment Variables
-- `GEMINI_API_KEY`: Required for AI-integrated features (though currently unutilized in core logic).
-- `DISABLE_HMR`: If set to `true` (standard in AI Studio environments), Hot Module Replacement is disabled to prevent flickering during agent-driven edits.
 
 ## Development Conventions
-
+- **Component Architecture:** Functional components with modern hooks.
-- **Component Architecture:** Functional components with modern hooks. All main application logic currently resides in `src/App.tsx`.
+- **State Management**: React `useState`, `useMemo`, and `useCallback` for optimized performance during large archive scans.
-- **Styling Strategy:** Utility-first CSS using Tailwind CSS v4. Styles are largely co-located with components.
+- **File Handling:** Privacy-focused client-side scanning of archive directories.
-- **Type Safety:** Strict TypeScript usage for all components and utility functions.
-- **Iconography:** Consistent use of `lucide-react` for all UI icons.
-- **Animations:** Smooth transitions and gestures powered by `motion/react`.
-- **File Handling:** Privacy-focused client-side scanning of archive directories using browser-native APIs.
