 ## Overview
 WooNooW is a hybrid WordPress + React SPA replacement for WooCommerce Admin. It focuses on performance, UX consistency, and extensibility with SSR-safe endpoints and REST-first design. The plugin integrates deeply with WooCommerce’s data store (HPOS ready) and provides a modern React-based dashboard and order management system.

 **Implementation Date:** November 11, 2025

 **Next Milestone:** Dynamic push notification URLs

+
+## 📧 Email Notification System Enhancements — November 19, 2025
+
+### ✅ Variable Dropdown in TipTap Editor - COMPLETE
+
+**Problem:** Users had to manually type `{variable_name}` placeholders in email templates.
+
+**Solution:** Added comprehensive variable dropdown with 40+ available variables.
+
+#### **Frontend Changes**
+
+**File:** `admin-spa/src/routes/Settings/Notifications/EditTemplate.tsx`
+
+**Added variables list** (lines 42-87):
+```typescript
+const availableVariables = [
+  // Order variables (14)
+  'order_number', 'order_id', 'order_date', 'order_total',
+  'order_subtotal', 'order_tax', 'order_shipping', 'order_discount',
+  'order_status', 'order_url', 'order_items_table',
+  'completion_date', 'estimated_delivery',
+  
+  // Customer variables (7)
+  'customer_name', 'customer_first_name', 'customer_last_name',
+  'customer_email', 'customer_phone',
+  'billing_address', 'shipping_address',
+  
+  // Payment variables (5)
+  'payment_method', 'payment_status', 'payment_date',
+  'transaction_id', 'payment_retry_url',
+  
+  // Shipping/Tracking variables (4)
+  'tracking_number', 'tracking_url',
+  'shipping_carrier', 'shipping_method',
+  
+  // URL variables (3)
+  'review_url', 'shop_url', 'my_account_url',
+  
+  // Store variables (6)
+  'site_name', 'site_title', 'store_name',
+  'store_url', 'support_email', 'current_year',
+];
+```
+
+**Features:**
+- ✅ Dropdown appears below TipTap editor
+- ✅ Shows all 40+ available variables
+- ✅ Click to insert at cursor position
+- ✅ Formatted as `{variable_name}`
+- ✅ Categorized by type (Order, Customer, Payment, etc.)
+
+---
+
+### ✅ Notification Page Reorganization - COMPLETE
+
+**Problem:** Flat card layout made it hard to scale for future recipient types (Affiliate, Merchant).
+
+**Solution:** Categorized cards into "Recipients" and "Channels" sections.
+
+#### **Frontend Changes**
+
+**File:** `admin-spa/src/routes/Settings/Notifications.tsx`
+
+**New Structure:**
+```
+📧 Notifications
+├── 👥 Recipients
+│   ├── Staff (Orders, Products, Customers)
+│   └── Customer (Orders, Shipping, Account)
+│   
+└── 📡 Channels
+    ├── Channel Configuration (Email, Push, WhatsApp, Telegram)
+    └── Activity Log (Coming soon)
+```
+
+**Benefits:**
+- ✅ Clear separation of concerns
+- ✅ Easy to add new recipients (Affiliate, Merchant)
+- ✅ Scalable structure
+- ✅ Better UX with section headers
+- ✅ Professional organization
+
+---
+
+### ✅ Email Card Styling Fixes - COMPLETE
+
+**Problem:** 
+1. `[card type="success"]` rendered with hero gradient (purple) instead of green
+2. List support verification needed
+
+**Solution:** Fixed card rendering in EmailRenderer.
+
+#### **Backend Changes**
+
+**File:** `includes/Core/Notifications/EmailRenderer.php` (lines 348-380)
+
+**Before:**
+```php
+if ($type === 'hero' || $type === 'success') {
+    // Both used same gradient ❌
+    $style .= ' background: linear-gradient(...)';
+}
+```
+
+**After:**
+```php
+if ($type === 'hero') {
+    // Hero: gradient background
+    $style .= ' background: linear-gradient(...)';
+}
+elseif ($type === 'success') {
+    // Success: green theme ✅
+    $style .= ' background-color: #f0fdf4; border-left: 4px solid #22c55e;';
+}
+elseif ($type === 'info') {
+    // Info: blue theme
+    $style .= ' background-color: #f0f7ff; border-left: 4px solid #0071e3;';
+}
+elseif ($type === 'warning') {
+    // Warning: orange theme
+    $style .= ' background-color: #fff8e1; border-left: 4px solid #ff9800;';
+}
+```
+
+**Card Types Now:**
+- `default`: white background
+- `hero`: gradient background (purple)
+- `success`: green background with left border ✅
+- `info`: blue background with left border
+- `warning`: orange background with left border
+
+**List Support:**
+- ✅ Already working in MarkdownParser (lines 132-141)
+- ✅ Supports: `*`, `-`, `•`, `✓`, `✔` as list markers
+- ✅ Properly converts to `<ul><li>` HTML
+
+---
+
+### 📊 Files Changed
+
+**Frontend:**
+- `admin-spa/src/routes/Settings/Notifications.tsx` - Card reorganization
+- `admin-spa/src/routes/Settings/Notifications/EditTemplate.tsx` - Variable dropdown
+
+**Backend:**
+- `includes/Core/Notifications/EmailRenderer.php` - Card styling fixes
+
+**Documentation:**
