+# Frontend Documentation
+
+The frontend is a modern, responsive dashboard designed for high visibility and aesthetic appeal.
+
+## Design Principles
+- **Glassmorphism**: Uses semi-transparent backgrounds with blur effects (`backdrop-filter`).
+- **Dark Mode**: Optimized for low-light environments (NOC/Dashboard style).
+- **Vibrant Accents**: Uses gradients and neon colors to highlight status and metrics.
+
+## Key Features
+- **Dynamic Gauges**: Built with `Chart.js` to show CPU and RAM usage.
+- **Status Badges**: Real-time color-coded badges (Online/Offline).
+- **Auto-Refresh**: Polls the `/api/status` endpoint every 1 minute.
+- **Loading State**: A smooth loading overlay that disappears once the first data batch is received.
+
+## UI Components
+- **Server Cards**: Detailed metrics for PC and Raspberry Pi.
+- **Web Services List**: Compact list of external services with latency tracking.
+- **Responsive Grid**: Automatically adjusts layout based on screen size.
