+# Modern Features Summary: Svelte 5 + SvelteKit 2 + Tailwind 4
+
+## 🎯 **Svelte 5 Runes Implementation**
+
+### State Management Revolution
+```typescript
+// OLD: Svelte 4 stores
+import { writable, derived } from 'svelte/store';
+export const webhookEvents = writable<WebhookEvent[]>([]);
+export const connectionStatus = writable<'connected' | 'disconnected'>('disconnected');
+
+// NEW: Svelte 5 runes
+let webhookEvents = $state<WebhookEvent[]>([]);
+let connectionStatus = $state<'connected' | 'disconnected' | 'connecting'>('disconnected');
+
+export const webhookStore = {
+  get events() { return webhookEvents; },
+  get status() { return connectionStatus; },
+  get totalEvents() { return webhookEvents.length; }, // Derived automatically
+  addEvent: (event) => { webhookEvents = [event, ...webhookEvents]; }
+};
+```
+
+### Reactive Derivations
+```typescript
+// Automatic reactivity with $derived
+let filteredEvents = $derived.by(() => {
+  let events = webhookStore.events;
+  if (searchQuery.trim()) {
+    events = events.filter(event => 
+      event.path.toLowerCase().includes(searchQuery.toLowerCase())
+    );
+  }
+  return events;
+});
+
+let eventsByMethod = $derived.by(() => {
+  const methods = new Map<string, number>();
+  webhookStore.events.forEach(event => {
+    methods.set(event.method, (methods.get(event.method) || 0) + 1);
+  });
+  return Array.from(methods.entries());
+});
+```
+
+### Side Effects with $effect
+```typescript
+// WebSocket connection status notifications
+$effect(() => {
+  if (webhookStore.status === 'connected') {
+    notificationStore.success('Connected', 'Real-time updates are active');
+  }
+});
+
+// Auto-refresh mechanism
+$effect(() => {
+  if (autoRefresh) {
+    const interval = setInterval(() => {
+      webhookStore.loadHistory();
+    }, 30000);
+    return () => clearInterval(interval);
+  }
+});
+```
+
+### Modern Component Props
+```typescript
+// OLD: export let prop syntax
+export let event: WebhookEvent;
+
+// NEW: $props() rune with TypeScript
+interface Props {
+  event: WebhookEvent;
+}
+let { event }: Props = $props();
+```
+
+### Event Handling Updates
+```typescript
+// OLD: on:click directive
+<button on:click={handleClick}>Click me</button>
+
+// NEW: onclick attribute (Svelte 5)
+<button onclick={handleClick}>Click me</button>
+```
+
+## 🚀 **SvelteKit 2 Enhancements**
+
+### Enhanced Request Handling
+```typescript
+// OLD: Destructured parameters
+export const POST: RequestHandler = async ({ request, params, url }) => {
+  // handler code
+};
+
+// NEW: Event object pattern
+export const POST: RequestHandler = async (event) => {
+  const { request, params, url } = event;
+  // Enhanced error handling and type safety
+};
+```
+
+### Modern Error Handling
+```typescript
+// OLD: throw error()
+if (!session?.user?.id) {
+  throw error(401, 'Unauthorized');
+}
+
+// NEW: Direct error() call
+if (!session?.user?.id) {
+  error(401, 'Unauthorized');
+}
+```
+
+### Enhanced Configuration
+```typescript
+// svelte.config.js - SvelteKit 2 features
+export default {
+  kit: {
+    adapter: adapter(),
+    alias: {
+      $stores: './src/lib/stores',
+      $components: './src/lib/components'
+    },
+    version: {
+      pollInterval: 300 // Enhanced version polling
+    }
+  },
+  compilerOptions: {
+    runes: true // Enable Svelte 5 runes
+  }
+};
+```
+
+## 🎨 **Tailwind 4 Modern Integration**
+
+### Vite Plugin Integration
+```typescript
+// vite.config.ts - Native Tailwind 4 support
+import tailwindcss from '@tailwindcss/vite';
+
+export default defineConfig({
+  plugins: [
+    sveltekit(),
+    tailwindcss() // Direct Vite plugin integration
+  ]
+});
+```
+
+### Enhanced Color System
+```typescript
+// tailwind.config.ts - Modern color palette
+export default {
+  theme: {
+    extend: {
+      colors: {
+        primary: { 50: '#eff6ff', 500: '#3b82f6', 900: '#1e3a8a' },
+        success: { 50: '#f0fdf4', 500: '#22c55e', 900: '#14532d' },
+        warning: { 50: '#fffbeb', 500: '#f59e0b', 900: '#78350f' },
+        danger: { 50: '#fef2f2', 500: '#ef4444', 900: '#7f1d1d' }
+      }
+    }
+  }
+} satisfies Config;
+```
+
+### CSS Import Simplification
+```css
+/* OLD: Multiple imports */
+@tailwind base;
+@tailwind components;
+@tailwind utilities;
+
+/* NEW: Single import */
+@import 'tailwindcss';
+
+/* Enhanced theme function usage */
+.custom-scrollbar::-webkit-scrollbar-thumb {
+  background: theme('colors.gray.400');
+}
+```
+
+### Modern Utility Classes
+```html
+<!-- Enhanced button components -->
+<button class="btn-primary"> <!-- Custom utility class -->
+<button class="bg-primary-600 hover:bg-primary-700 text-white px-4 py-2 rounded-lg font-medium transition-colors focus-ring">
+
+<!-- Semantic color usage -->
+<div class="bg-success-50 text-success-800"> <!-- Success state -->
+<div class="bg-danger-50 text-danger-800">   <!-- Error state -->
+```
+
+## 🔧 **Advanced Modern Features**
+
+### 1. **Reactive Notifications System**
+```typescript
+// Svelte 5 runes-based notification system
+let notifications = $state<Notification[]>([]);
+
+export const notificationStore = {
+  get notifications() { return notifications; },
+  success(title: string, message?: string) {
+    // Auto-removing notifications with runes
+  }
+};
+```
+
+### 2. **Enhanced Error Boundaries**
+```svelte
+<!-- Modern error boundary with snippets -->
+<ErrorBoundary fallback="Something went wrong">
+  {#snippet children()}
+    <slot />
+  {/snippet}
+</ErrorBoundary>
+```
+
+### 3. **Smart Loading States**
+```svelte
+<!-- Conditional loading with shimmer effects -->
+{#if isCalculating}
+  <div class="loading-shimmer w-16 h-8 rounded"></div>
+{:else}
+  {metricsData.totalEvents}
+{/if}
+```
+
+### 4. **Real-time Metrics Dashboard**
+```typescript
+// Automatic metric calculations with derived state
+let eventsByMethod = $derived.by(() => {
+  const methods = new Map<string, number>();
+  webhookStore.events.forEach(event => {
+    methods.set(event.method, (methods.get(event.method) || 0) + 1);
+  });
+  return Array.from(methods.entries()).sort((a, b) => b[1] - a[1]);
+});
+```
+

+  }
+});
+```
+
+### Live Metrics
+```typescript
+// Real-time calculations
