 - a system-WebView-based runtime model instead of shipping a bundled browser per app
 
 ### Key Features
-- **Extremely Lightweight:** Generated binaries are tiny (~4-6 MB) and RAM consumption is minimal.
+- **System-WebView Runtime Model:** Generated wrappers stay small because Deskify relies on the system WebView instead of bundling a browser runtime per app.
 - **Automatic Icon Fetching:** Scrapes high-quality 128x128 favicons automatically using the Google Favicon API.
 - **XDG-Compliant System Integration:** Safely creates `.desktop` entries in `~/.local/share/applications` and manages application icons in `~/.local/share/icons/hicolor/`.
 - **Wayland/X11 Ready:** Perfectly binds `StartupWMClass` to ensure your DE groups the app exactly to its custom icon (no generic gear icons in GNOME/KDE taskbars).
