+## Tech Stack
+
+| Layer | Technology |
+|-------|------------|
+| Frontend | Vite + React 18 |
+| Styling | Tailwind CSS |
+| Animation | canvas-confetti |
+| Container | Multi-stage Dockerfile → nginx:alpine |
+| Orchestration | Kubernetes with Traefik ingress |
+
+## Frontend Components
+
+```
+App.jsx
+├── BirthdayBanner.jsx     # Hero with name + roast message + confetti
+└── RoastGallery.jsx       # Grid of photos with captions
+    └── RoastCard.jsx      # Individual photo + caption
+```
+
+### BirthdayBanner
+- Large "Happy Birthday [Name]!" heading
+- Roast subtitle message
+- Confetti animation on page load
+- Click-to-trigger more confetti
+
+### RoastGallery
+- Responsive CSS grid (2-3 cols mobile, 4-5 cols desktop)
+- Cards with hover effects
+
+### RoastCard
+- Image with aspect ratio
+- Caption below or overlay
+- Hover animation (scale/shadow)
+
+## Static Assets
+
+Images stored in `public/images/` with captions configured in `public/roasts.json`:
+
+```json
+[
+  { "image": "roast-1.jpg", "caption": "Khoảnh khắc huyền thoại 😂" },
+  { "image": "roast-2.jpg", "caption": "Gương mặt khi quên đóng bài tập" }
+]
+```
+
+- UTF-8 encoding for Vietnamese captions
+- Add photos: drop file → add JSON entry → rebuild
+
+## Container Setup
+
+### Dockerfile (multi-stage)
+
+```dockerfile
+# Build stage
+FROM node:20-alpine AS builder
+WORKDIR /app
+COPY package*.json ./
+RUN npm ci
+COPY . .
+RUN npm run build
+
+# Runtime stage
+FROM nginx:alpine
+COPY --from=builder /app/dist /usr/share/nginx/html
+COPY nginx.conf /etc/nginx/conf.d/default.conf
+EXPOSE 80
+```
+
+### nginx.conf
+- Static file serving
+- Gzip compression
+- SPA fallback
+
+## Kubernetes Deployment
+
+```
+k8s/
+├── deployment.yaml      # Nginx pod, 1-2 replicas
+├── service.yaml         # ClusterIP on port 80
+└── ingress.yaml         # Traefik ingress for cmsn-b-linh.duylai.duckdns.org
+```
+
+### Deployment
+- Image: registry/cmsn-b-linh:latest
+- Replicas: 1
+- Resources: minimal (50m CPU, 64Mi RAM)
+
+### Ingress (Traefik)
+- Host: cmsn-b-linh.duylai.duckdns.org
+- Traefik-compatible annotations
+- Optional: TLS via cert-manager

+# Birthday Roast Gallery Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Build a birthday roast gallery website with photos, Vietnamese captions, confetti animation, and Kubernetes deployment manifests.
+
+**Architecture:** Vite + React frontend with Tailwind CSS, served by Nginx in a minimal Alpine container. Multi-stage Docker build for small image size. Kubernetes manifests for Traefik ingress deployment.
+
+**Tech Stack:** React 18, Vite, Tailwind CSS, canvas-confetti, nginx:alpine, Kubernetes
+
+---
+
+### Task 1: Project Scaffold and Dependencies
+
+**Files:**
+- Create: `package.json`
+- Create: `vite.config.js`
+- Create: `tailwind.config.js`
+- Create: `postcss.config.js`
+- Create: `index.html`
+- Create: `src/main.jsx`
+- Create: `src/index.css`
+- Create: `.gitignore`
+
+**Step 1: Initialize npm project and install dependencies**
+
+```bash
+npm init -y
+npm install react react-dom
+npm install -D vite @vitejs/plugin-react tailwindcss postcss autoprefixer canvas-confetti
+```
+
+**Step 2: Create vite.config.js**
+
+```javascript
+import { defineConfig } from 'vite'
+import react from '@vitejs/plugin-react'
+
+export default defineConfig({
+  plugins: [react()],
+})
+```
+
+**Step 3: Create tailwind.config.js**
+
+```bash
+npx tailwindcss init -p
+```
+
+Then update `tailwind.config.js`:
+
+```javascript
+/** @type {import('tailwindcss').Config} */
+export default {
+  content: [
+    "./index.html",
+    "./src/**/*.{js,ts,jsx,tsx}",
+  ],
+  theme: {
+    extend: {},
+  },
+  plugins: [],
+}
+```
+
+**Step 4: Create postcss.config.js**
+
+```javascript
+export default {
+  plugins: {
+    tailwindcss: {},
+    autoprefixer: {},
+  },
+}
+```
+
+**Step 5: Create index.html**
+
+```html
+<!DOCTYPE html>
+<html lang="vi">
+  <head>
+    <meta charset="UTF-8" />
+    <link rel="icon" type="image/svg+xml" href="/vite.svg" />
+    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
+    <title>Happy Birthday Linh! 🎂</title>
+  </head>
+  <body>
+    <div id="root"></div>
+    <script type="module" src="/src/main.jsx"></script>
+  </body>
+</html>
+```
+
+**Step 6: Create src/main.jsx**
+
+```javascript
+import React from 'react'
+import ReactDOM from 'react-dom/client'
+import App from './App.jsx'
+import './index.css'
+
+ReactDOM.createRoot(document.getElementById('root')).render(
+  <React.StrictMode>
+    <App />
+  </React.StrictMode>,
+)
+```
+
+**Step 7: Create src/index.css**
+
+```css
+@tailwind base;
+@tailwind components;
+@tailwind utilities;
+```
+
+**Step 8: Create .gitignore**
+
+```
+node_modules
+dist
+.DS_Store
+*.local
+```
+
+**Step 9: Update package.json scripts**
+
+Add these scripts to `package.json`:
+
+```json
+"scripts": {
+  "dev": "vite",
+  "build": "vite build",
+  "preview": "vite preview"
+}
+```
+
+**Step 10: Test the setup**
+
+```bash
+npm run dev
+```
+
+Expected: Dev server starts at http://localhost:5173 (will show error since App.jsx doesn't exist yet - that's ok)
+
+**Step 11: Commit**
+
+```bash
+git init
+git add .
+git commit -m "chore: initialize Vite + React + Tailwind project"
+```
+
+---
+
+### Task 2: Create RoastCard Component
+
+**Files:**
+- Create: `src/components/RoastCard.jsx`
+
+**Step 1: Create the RoastCard component**
+
+```jsx
+export default function RoastCard({ image, caption }) {
+  return (
+    <div className="group relative overflow-hidden rounded-xl shadow-lg hover:shadow-2xl transition-all duration-300 hover:scale-105 bg-white">
+      <div className="aspect-square overflow-hidden">
+        <img
+          src={`/images/${image}`}
+          alt={caption}
+          className="w-full h-full object-cover transition-transform duration-300 group-hover:scale-110"

+          {caption}
+        </p>
+      </div>
+    </div>
+  )
+}
+```
+
+**Step 2: Verify syntax**
+
+```bash
+npm run build
+```
+
+Expected: Build succeeds (may warn about unused component)
