+## 🚀 Standalone Admin Mode — November 5, 2025
+
+### ✅ COMPLETE - Three Admin Modes Implemented
+
+**Goal:** Provide flexible admin interface access with three distinct modes: normal (wp-admin), fullscreen, and standalone.
+
+### 🎯 Three Admin Modes
+
+#### **1. Normal Mode (wp-admin)**
+- **URL:** `/wp-admin/admin.php?page=woonoow`
+- **Layout:** WordPress admin sidebar + WooNooW SPA
+- **Use Case:** Traditional WordPress admin workflow
+- **Features:**
+  - WordPress admin bar visible
+  - WordPress sidebar navigation
+  - WooNooW SPA in main content area
+  - Settings submenu hidden (use WooCommerce settings)
+
+#### **2. Fullscreen Mode**
+- **Toggle:** Fullscreen button in header
+- **Layout:** WooNooW SPA only (no WordPress chrome)
+- **Use Case:** Focus mode for order processing
+- **Features:**
+  - Maximized workspace
+  - Distraction-free interface
+  - All WooNooW features accessible
+  - Settings submenu hidden
+
+#### **3. Standalone Mode** ✨ NEW
+- **URL:** `https://yoursite.com/admin`
+- **Layout:** Complete standalone application
+- **Use Case:** Quick daily access, mobile-friendly
+- **Features:**
+  - Custom login page (`/admin#/login`)
+  - WordPress authentication integration
+  - Settings submenu visible (SPA settings pages)
+  - "WordPress" button to access wp-admin
+  - "Logout" button in header
+  - Admin bar link in wp-admin to standalone
+
+### 🔧 Implementation Details
+
+#### **Backend Changes**
+
+**File:** `includes/Admin/StandaloneAdmin.php`
+- Handles `/admin` and `/admin/` requests
+- Renders standalone HTML template
+- Localizes `WNW_CONFIG` with `standaloneMode: true`
+- Provides authentication state
+- Includes store settings (currency, formatting)
+
+**File:** `includes/Admin/Menu.php`
+- Added admin bar link to standalone mode
+- Icon: `dashicons-store`
+- Only visible to users with `manage_woocommerce` capability
+
+**File:** `includes/Api/AuthController.php`
+- Login endpoint using native WordPress authentication
+- Sequence: `wp_authenticate()` → `wp_clear_auth_cookie()` → `wp_set_current_user()` → `wp_set_auth_cookie()` → `do_action('wp_login')`
+- Ensures session persistence between standalone and wp-admin
+
+#### **Frontend Changes**
+
+**File:** `admin-spa/src/App.tsx`
+- `AuthWrapper` component handles authentication
+- Login/logout flow with page reload
+- "WordPress" button in header (standalone only)
+- "Logout" button in header (standalone only)
+
+**File:** `admin-spa/src/routes/Login.tsx`
+- Custom login form
+- Username/password authentication
+- Redirects to dashboard after login
+- Page reload to pick up fresh cookies/nonces
+
+**File:** `admin-spa/src/nav/tree.ts`
+- Dynamic settings submenu using getter
+- Only shows in standalone mode: `get children() { return isStandalone ? [...] : [] }`
+- Dashboard path: `/dashboard` (with redirect from `/`)
+
+### 📊 Navigation Structure
+
+**Standalone Mode Settings:**
+```
+Settings
+├── WooNooW (main settings)
+├── General (store settings)
+├── Payments (gateways)
+├── Shipping (zones, methods)
+├── Products (inventory)
+├── Tax (rates)
+├── Accounts & Privacy
+├── Emails (templates)
+├── Advanced (bridge to wp-admin)
+├── Integration (bridge to wp-admin)
+├── Status (bridge to wp-admin)
+└── Extensions (bridge to wp-admin)
+```
+
+**Strategy:** Option A - Everyday Use Dashboard
+- Focus on most-used settings
+- Bridge to wp-admin for advanced settings
+- Extensible for 3rd party plugins
+- Coexist with WooCommerce
+
+### 🔐 Authentication Flow
+
+**Standalone Login:**
+1. User visits `/admin`
+2. Not authenticated → redirect to `/admin#/login`
+3. Submit credentials → `POST /wp-json/woonoow/v1/auth/login`
+4. Backend sets WordPress auth cookies
+5. Page reload → authenticated state
+6. Access all WooNooW features
+
+**Session Persistence:**
+- Login in standalone → logged in wp-admin ✅
+- Login in wp-admin → logged in standalone ✅
+- Logout in standalone → logged out wp-admin ✅
+- Logout in wp-admin → logged out standalone ✅
+
+### 📱 Cross-Navigation
+
+**From Standalone to wp-admin:**
+- Click "WordPress" button in header
+- Opens `/wp-admin` in same tab
+- Session persists
+
+**From wp-admin to Standalone:**
+- Click "WooNooW" in admin bar
+- Opens `/admin` in same tab
+- Session persists
+
+### ✅ Features Completed
+
+- [x] Standalone mode routing (`/admin`)
+- [x] Custom login page
+- [x] WordPress authentication integration
+- [x] Session persistence
+- [x] Settings submenu (standalone only)
+- [x] WordPress button in header
+- [x] Logout button in header
+- [x] Admin bar link to standalone
+- [x] Dashboard path consistency (`/dashboard`)
+- [x] Dynamic navigation tree
+- [x] Settings placeholder pages
+- [x] Documentation updates

+WooNooW provides **three distinct admin interface modes** to accommodate different workflows and user preferences:
+
+### **1. Normal Mode (wp-admin)**
+- **Access:** `/wp-admin/admin.php?page=woonoow`
+- **Layout:** Traditional WordPress admin with WooNooW SPA in content area
+- **Use Case:** Standard WordPress admin workflow
+- **Features:**
+  - WordPress admin bar and sidebar visible
+  - Full WordPress admin functionality
+  - WooNooW SPA integrated seamlessly
+  - Settings submenu hidden (use WooCommerce settings)
+- **When to use:** When you need access to other WordPress admin features alongside WooNooW
+
+### **2. Fullscreen Mode**
+- **Access:** Toggle button in WooNooW header
+- **Layout:** WooNooW SPA only (no WordPress chrome)
+- **Use Case:** Focused work sessions, order processing
+- **Features:**
+  - Maximized workspace
+  - Distraction-free interface
+  - All WooNooW features accessible
+  - Settings submenu hidden
+- **When to use:** When you want to focus exclusively on WooNooW tasks
+
+### **3. Standalone Mode** ✨
+- **Access:** `https://yoursite.com/admin`
+- **Layout:** Complete standalone application with custom login
+- **Use Case:** Quick daily access, mobile-friendly, bookmark-able
+- **Features:**
+  - Custom login page (`/admin#/login`)
+  - WordPress authentication integration
+  - Settings submenu visible (SPA settings pages)
+  - "WordPress" button to access wp-admin
+  - "Logout" button in header
+  - Admin bar link in wp-admin to standalone
+  - Session persistence across modes
+- **When to use:** As your primary WooNooW interface, especially on mobile or for quick access
+
+### **Mode Switching**
+- **From wp-admin to Standalone:** Click "WooNooW" in admin bar
+- **From Standalone to wp-admin:** Click "WordPress" button in header
+- **To Fullscreen:** Click fullscreen toggle in any mode
+- **Session persistence:** Login state is shared across all modes
+
+### **Settings Submenu Behavior**
+- **Normal Mode:** No settings submenu (use WooCommerce settings in wp-admin)
+- **Fullscreen Mode:** No settings submenu
+- **Standalone Mode:** Full settings submenu visible with SPA pages
+
+**Implementation:** Settings submenu uses dynamic getter in `admin-spa/src/nav/tree.ts`:
+```typescript
+get children() {
+  const isStandalone = (window as any).WNW_CONFIG?.standaloneMode;
+  if (!isStandalone) return [];
+  return [ /* settings items */ ];

 **WooNooW** is a modern experience layer for WooCommerce — enhancing UX, speed, and reliability **without data migration**.  
 It keeps WooCommerce as the core engine while providing a modern React-powered interface for both the **storefront** (cart, checkout, my‑account) and the **admin** (orders, dashboard).
 
+**Three Admin Modes:**
+- **Normal Mode:** Traditional wp-admin integration (`/wp-admin/admin.php?page=woonoow`)
+- **Fullscreen Mode:** Distraction-free interface (toggle in header)
