+# AGENTS GUIDE (Updated with Atomic Design)
+
+## 1) Kiến trúc project
+
+Dự án sử dụng **Next.js App Router** với **Atomic Design Pattern** cho UI
+components.
+
+### `app/` - Routes & Pages
+
+Chứa route/page/layout theo Next.js App Router.
+
+- **`layout.tsx`** - Root layout toàn app (Header + Providers + Footer wrapper)
+- **`providers.tsx`** - Client component gắn 3 providers: AuthProvider,
+  MenuProvider, CartProvider
+- **`globals.css`** - Global styles + CSS variables + Tailwind imports
+- **Route groups:**
+  - **`(main)/`** - Main shopping interface (duyệt menu, đăng nhập, đăng ký,
+    thanh toán)
+  - **`(feed)/`** - Feed/discovery page (khám phá quán)
+  - **`(manager)/`** - Manager dashboard (quản lý sản phẩm, đơn hàng) - **[ĐANG
+    PHÁT TRIỂN]**
+- **Tài liệu:** `app/APP.md` - Chi tiết routes, pages, CSS tokens
+
+### `components/` - Reusable UI Components (Atomic Design)
+
+Chứa UI components được tổ chức theo **Atomic Design Pattern** với 5 cấp độ:
+
+#### **ATOMS** (`components/atoms/`)
+
+**Khối xây dựng cơ bản, không chia nhỏ hơn được.**
+
+Các component cơ bản, tái sử dụng cao, không logic phức tạp:
+
+- **`buttons/`** - Button, IconButton
+- **`inputs/`** - TextInput, NumberInput, Checkbox
+- **`badges/`** - Badge, PriceBadge, StatusBadge
+- **`icons/`** - StarIcon, CartIcon, SearchIcon, etc.
+- **`typography/`** - Heading, Text, Caption
+- **`dividers/`** - Divider
+- **`loaders/`** - Spinner, Skeleton
+
+**Đặc điểm:**
+
+- ✅ Pure props-based, no logic
+- ✅ Full TypeScript typing
+- ✅ Reusable across entire project
+- ✅ No context/hooks
+- 📄 Tài liệu: `components/atoms/ATOMS.md`
+
+#### **MOLECULES** (`components/molecules/`)
+
+**Nhóm atoms đơn giản hoạt động cùng nhau.**
+
+Kết hợp multiple atoms, có thể có state đơn giản (open/close):
+
+- **`form-groups/`** - FormField (input + label + error)
+- **`cards/`** - ProductCard, ShopCard, ReviewCard
+- **`ratings/`** - RatingStars, RatingInput
+- **`price-display/`** - PriceTag, PriceRange
+- **`search-bar/`** - SearchInput, SearchBar
+- **`breadcrumb/`** - Breadcrumb
+- **`tabs/`** - TabGroup, Tab
+
+**Đặc điểm:**
+
+- ✅ Combines atoms
+- ✅ Simple state (useState for UI)
+- ✅ No business logic
+- ✅ Reusable in multiple contexts
+- ❌ No global context (useAuth, useCart)
+- 📄 Tài liệu: `components/molecules/MOLECULES.md`
+
+#### **ORGANISMS** (`components/organisms/`)
+
+**Khu vực UI phức tạp, riêng biệt, có logic riêng.**
+
+Sections phức tạp kết hợp molecules + atoms, có logic, data filtering:
+
+- **`navigation/`** - Navbar, CategoryMenu
+- **`cart/`** - CartFab, CartSummary, CartList
+- **`product-grid/`** - ProductGrid, ProductFilters
+- **`forms/`** - LoginForm, RegisterForm, CheckoutForm, ReviewForm
+- **`modals/`** - ReviewModal, ConfirmModal
+- **`shop-grid/`** - ShopGrid, ShopFilters
+- **`hero-section/`** - HeroSection
+- **`featured-section/`** - FeaturedProducts, FeaturedShops
+
+**Đặc điểm:**
+
+- ✅ Complex UI sections
+- ✅ Can use contexts (useAuth, useCart, useMenu)
+- ✅ Business logic (filtering, sorting)
+- ✅ Always "use client"
+- ❌ Not directly reusable (section-specific)
+- 📄 Tài liệu: `components/organisms/ORGANISMS.md`
+
+#### **TEMPLATES** (`components/templates/`)
+
+**Bố cục cấp trang, cấu trúc nội dung.**
+
+Page layouts, không có data cụ thể, children composition:
+
+- **`main-layout/`** - MainLayout (header + sidebar + content + footer)
+- **`feed-layout/`** - FeedLayout
+- **`manager-layout/`** - ManagerLayout
+- **`checkout-layout/`** - CheckoutLayout
+- **`auth-layout/`** - AuthLayout
+
+**Đặc điểm:**
+
+- ✅ Page-level layout structure
+- ✅ Composition of organisms
+- ✅ No data fetching
+- ✅ Children prop pattern
+- ❌ No hardcoded data
+- 📄 Tài liệu: `components/templates/TEMPLATES.md`
+
+#### **PAGES** (`app/*/page.tsx`)
+
+**Phiên bản cụ thể với dữ liệu thật.**
+
+Route-specific pages, sử dụng templates + organisms:
+
+- **`app/(main)/page.tsx`** - Main shopping page
+- **`app/(main)/checkout/page.tsx`** - Checkout page
+- **`app/(feed)/page.tsx`** - Feed/discovery page
+- **`app/(manager)/products/page.tsx`** - Manager dashboard
+
+**Đặc điểm:**
+
+- ✅ Route-specific logic
+- ✅ Data integration
+- ✅ Context usage
+- ✅ State orchestration
+- ❌ No UI component definitions
+
+**Tài liệu chi tiết:**
+
+- `components/ATOMIC_DESIGN.md` - Full Atomic Design structure guide
+- `components/atoms/ATOMS.md` - Atoms inventory & props
+- `components/molecules/MOLECULES.md` - Molecules inventory & usage
+- `components/organisms/ORGANISMS.md` - Organisms inventory & logic
+- `components/templates/TEMPLATES.md` - Templates structure
+
+### `layouts/` - Layout Components
+
+Chứa layout cấp root (không phải Atomic Design templates):
+
+- **`header.tsx`** - Sticky top bar với brand (logo + shop name) + auth status
+- **`footer.tsx`** - Footer với 3 sections: brand info, social links, WiFi card
+- **Tài liệu:** `layouts/LAYOUTS.md` - Responsive design, CSS variables
+
+### `lib/` - Shared Logic & Data
+
+Chứa logic dùng chung, context, constants, types:
+
+- **`types.ts`** - TypeScript interfaces: User, Product, MenuCategory, Shop,
+  ShopInfo
+- **`constants.ts`** - Mock data: MOCK_PRODUCTS (18 items), MOCK_SHOPS (5),
+  MOCK_USERS, MENU_CATEGORIES (8), SHOP_INFO, SOCIAL_LINKS
+- **`auth-context.tsx`** - AuthProvider + useAuth() hook (login, logout,
+  register)
+- **`cart-context.tsx`** - CartProvider + useCart() hook (add, remove, quantity
+  operations)
+- **`menu-context.tsx`** - MenuProvider + useMenu() hook (category state)
+- **Tài liệu:** `lib/LIB.md` - Chi tiết types, constants, contexts
+
+### `public/` - Static Assets
+
+Chứa static assets:
+
+- **`favicon/`** - Favicon files
+- **`imgs/`** - Logo, product images (organized in `products/` subfolder)
+
+### `scripts/` - Internal Scripts
+
+Chứa script nội bộ:
+
+- **`release.ts`** - Semantic release script
+
+### `types/` - Global Types
+
+Chứa type dùng chung cấp project:
+
+- **`css.d.ts`** - TypeScript declarations cho CSS modules
+
+### Root Config Files
+
+- **`package.json`** - Dependencies (Next.js 16.1.7, React 19.2.3, Tailwind
+  4.2.2, TypeScript)
+- **`tsconfig.json`** - TypeScript config
+- **`next.config.ts`** - Next.js config
+- **`tailwind.config.ts`** - Tailwind CSS config (v4)
+- **`postcss.config.mjs`** - PostCSS config
+- **`eslint.config.ts`** - ESLint rules
+- **`.prettierrc`** - Prettier formatting
+- **`release.config.ts`** - Semantic release config
+
+---
+
+## 2) Code convention (Naming, format, style guide)
+
+### Naming & File Organization
+
+- **React components:** `PascalCase` (e.g., `Button.tsx`, `ProductCard.tsx`)
+- **Context/util files:** `kebab-case` (e.g., `auth-context.tsx`,
+  `menu-context.tsx`)
+- **Type files:** `ComponentName.types.ts` (e.g., `Button.types.ts`)
+- **Variables/functions:** `camelCase`
+- **Types/Interfaces:** `PascalCase`
+- **Routes:** Follow folder structure in `app/` (URL = folder path)
+- **Imports:** Use absolute paths with `@/` alias (e.g.,
+  `import { Button } from "@/components/atoms/buttons/Button"`)
+
+### Atomic Design File Structure
+
+```
+components/
+├── atoms/
+│   ├── buttons/
+│   │   ├── Button.tsx
+│   │   └── Button.types.ts
+│   ├── typography/
+│   │   ├── Text.tsx
+│   │   └── Text.types.ts
+│   └── index.ts (barrel export)
+├── molecules/
+│   ├── cards/
+│   │   ├── ProductCard.tsx
+│   │   └── Card.types.ts
+│   └── index.ts

+│   ├── main-layout/
+│   │   ├── MainLayout.tsx
+│   │   └── MainLayout.types.ts
+│   └── index.ts
+└── ATOMIC_DESIGN.md
+```
+
+### Format & Linting
+
+- **Language:** TypeScript (.ts, .tsx) for all files
+- **Formatter:** Prettier (config: `.prettierrc`)
+  - Import sorting: `@trivago/prettier-plugin-sort-imports`
+  - Tailwind class sorting: `prettier-plugin-tailwindcss`
+- **Linter:** ESLint (config: `eslint.config.ts`, extends `next` rules)
+- **Code style:**
+  - Clear, self-documenting code
+  - Separate concerns by module/file
+  - Avoid code duplication
+  - Keep imports clean (no dead code)
+  - Use `"use client"` only where needed (interactive components)
+
+### Styling & UI
+
+- **Framework:** Tailwind CSS v4.2.2
+- **CSS Variables:** Defined in `globals.css` at `:root`
+  - Colors: `--color-primary`, `--color-primary-dark`, `--color-accent`,
+    `--color-bg-*`, `--color-text-*`, `--color-border-*`, `--color-shadow-*`
+  - Spacing: `--spacing-header-height` (72px)
+  - Use in Tailwind: `bg-[color:var(--color-primary)]`,
+    `text-[color:var(--color-text-primary)]`
+- **Icons:** FontAwesome (free CDN icons via `<i class="fa-solid fa-...">`)
+- **Images:** Next.js `Image` component from `next/image`
+- **Dark mode:** CSS variables support dark mode (can override `:root` values in
+  `@media (prefers-color-scheme: dark)`)
+
+### Responsive Design
+
+- **Breakpoints (Tailwind):** sm (640px), md (768px), lg (1024px), xl (1280px),
+  2xl (1536px)
+- **Every new UI feature must be responsive:**
+  - Mobile (<640px): Single column, stacked layout, collapsed sidebar
+  - Tablet (640px-1024px): 2-column layout, adjusted grid
+  - Desktop (1024px+): Multi-column, expanded sidebar, comfortable spacing
+- **Mobile-first approach:** Write base styles for mobile, then add `sm:`,
+  `md:`, `lg:`, `xl:` prefixes for larger screens
+- **Example:** `className="w-full sm:w-1/2 md:w-1/3 lg:w-1/4"`
+
+---
+
+## 3) Quy tắc quan trọng
+
+### Markdown Documentation Updates
+
+**Luôn update các file markdown trong folder liên quan khi hoàn thành task:**
+
+| Folder Modified         | Update File                         | Content to Add/Update                       |
+| ----------------------- | ----------------------------------- | ------------------------------------------- |
+| `components/atoms/`     | `components/atoms/ATOMS.md`         | Atom props, variants, usage examples        |
+| `components/molecules/` | `components/molecules/MOLECULES.md` | Molecule props, composition, usage          |
+| `components/organisms/` | `components/organisms/ORGANISMS.md` | Organism logic, contexts used, features     |
+| `components/templates/` | `components/templates/TEMPLATES.md` | Template structure, responsive layout       |
+| `app/`                  | `app/APP.md`                        | Routes, pages, CSS tokens                   |
+| `layouts/`              | `layouts/LAYOUTS.md`                | Layout structure, responsive patterns       |
+| `lib/`                  | `lib/LIB.md`                        | New types, constants, contexts              |
+| **Root**                | `ATOMIC_DESIGN.md`                  | Overall structure, patterns, best practices |
+
+**Quy trình:**
+
+1. Hoàn thành task/feature
+2. Update file `.md` tương ứng trong folder
+3. Commit code + markdown updates cùng lúc
+4. Push to branch
+
+### Type Safety & Data Flow
+
+- **Always use TypeScript** - no plain `any` types
+- **Mock data first** - Use `lib/constants.ts` for development, replace with API
+  later
+- **Contexts for state sharing:**
+  - `AuthContext` (lib/auth-context.tsx) - User state + auth operations
+  - `CartContext` (lib/cart-context.tsx) - Shopping cart + operations
+  - `MenuContext` (lib/menu-context.tsx) - Active category state
+- **localStorage keys:** `coffee-shop-user`, `coffee-shop-cart` (defined in
+  contexts)
+
+### Component Development (Atomic Design)
+
+#### Creating an Atom
+
+1. Identify the basic building block needed (button, input, text, icon)
+2. Create `atoms/category/ComponentName.tsx`
+3. Create `atoms/category/ComponentName.types.ts` with props interface
+4. No business logic, pure props-based
+5. Add to `atoms/index.ts` barrel export
+6. Document in `atoms/ATOMS.md`
+
+```tsx
+// Example: atoms/buttons/Button.tsx
+import type { ButtonProps } from "./Button.types";
+
+export default function Button({ variant = "primary", ...props }: ButtonProps) {
+  return <button className={variants[variant]} {...props} />;
+}
+```
+
+#### Creating a Molecule
+
+1. Identify which atoms compose this molecule
+2. Create `molecules/category/ComponentName.tsx`
+3. Create `molecules/category/ComponentName.types.ts`
+4. Can use useState for simple UI state
+5. No global context usage
+6. Add to `molecules/index.ts` barrel export
+7. Document in `molecules/MOLECULES.md`
+
+```tsx
+// Example: molecules/cards/ProductCard.tsx
+"use client";
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+
+import type { ProductCardProps } from "./Card.types";
+
+export default function ProductCard({
+  product,
+  onAddToCart,
+}: ProductCardProps) {
+  return (
+    <div className="rounded-lg border">
+      {/* atoms composition */}
+      <Button onClick={() => onAddToCart(product)}>Add</Button>
+    </div>
+  );
+}
+```
+
+#### Creating an Organism
+
+1. Identify complex section (product grid, form, modal content)
+2. Create `organisms/section-type/ComponentName.tsx`
+3. Create `organisms/section-type/ComponentName.types.ts`
+4. Can use contexts (useAuth, useCart, useMenu)
+5. Contains business logic (filtering, sorting, validation)
+6. Always use `"use client"`
+7. Add to `organisms/index.ts` barrel export
+8. Document in `organisms/ORGANISMS.md`
+
+```tsx
+// Example: organisms/product-grid/ProductGrid.tsx
+"use client";
+import { useCart } from "@/lib/cart-context";
+import { useMenu } from "@/lib/menu-context";
+import ProductCard from "@/components/molecules/cards/ProductCard";
+
+export default function ProductGrid() {
+  const { activeCategory } = useMenu();
+  const { addToCart } = useCart();
+
+  const filtered = products.filter(p =>
+    activeCategory === "all" || p.category === activeCategory
+  );
+
+  return (
+    <div className="grid grid-cols-1 md:grid-cols-3">
+      {filtered.map(p => <ProductCard key={p.id} {...} />)}
+    </div>
+  );
+}
+```
+
+#### Creating a Template
+
+1. Identify page-level layout structure
+2. Create `templates/layout-type/TemplateName.tsx`
+3. Create `templates/layout-type/TemplateName.types.ts`
+4. No data fetching, purely structural
+5. Compose organisms + layout sections
+6. Use children prop pattern
+7. Add to `templates/index.ts` barrel export
+8. Document in `templates/TEMPLATES.md`
+
+```tsx
+// Example: templates/main-layout/MainLayout.tsx
+import Navbar from "@/components/organisms/navigation/Navbar";
+import Header from "@/layouts/header";
+
+import type { MainLayoutProps } from "./MainLayout.types";
+
+export default function MainLayout({ children }: MainLayoutProps) {
+  return (
+    <div className="flex min-h-screen flex-col">
+      <Header />
+      <div className="flex flex-1">
+        <nav className="hidden w-64 md:block">
+          <Navbar />
+        </nav>
+        <main className="flex-1">{children}</main>
+      </div>
+    </div>
+  );
+}
+```
+
+### Client vs Server Components
+
+- **Atoms:** Server by default, `"use client"` if interactive (Button, Input)
+- **Molecules:** `"use client"` if state needed, server if pure display
+- **Organisms:** Always `"use client"` (logic, contexts)
+- **Templates:** Server by default (layout), children can be client
+- **Pages:** Depends on needs (route-specific logic = client)
+
+### Testing & Quality
+
+- **Responsive testing:** Test on mobile (< 640px), tablet (768px), desktop
+  (1024px+)
+- **Accessibility:** Images have alt text, buttons have semantic HTML,
+  sufficient contrast
+- **Performance:** Use Next.js Image component, optimize imports, lazy-load
+  organisms
+- **Error handling:** Validate user input at system boundaries
+
+### Git & Commits
+
+- **Commit message:** Follow conventional commits (`feat:`, `fix:`, `docs:`,
+  `style:`, `refactor:`)
+- **Before pushing:** Ensure `npm run lint` and `npm run format` pass locally
+- **Markdown updates:** Include in same commit as code changes
+- **Branch naming:** Feature branches = `feature_<name>` (e.g.,
+  `feature_atomic_refactor`)

+## 4) Quick Reference Guide for AI
+
+### Atomic Design Cheat Sheet
+
+```
+ATOM              → Basic building block (Button, Text, Icon)
+MOLECULE          → Atoms group (ProductCard, FormField)
+ORGANISM          → Complex section (ProductGrid, LoginForm)
+TEMPLATE          → Page layout (MainLayout, CheckoutLayout)
+PAGE              → Specific route (app/*/page.tsx)
+```
+
+### Component Decision Tree
+
+```
+Is it a basic UI element?
+  ├─ YES → ATOM (Button, Text, Icon, Input, Badge)
+  └─ NO → Is it a composition of atoms?
+          ├─ YES → MOLECULE (Card, FormField, SearchBar)
+          └─ NO → Is it a complex section with logic/context?
+                  ├─ YES → ORGANISM (ProductGrid, LoginForm, Modal)
+                  └─ NO → Is it a page-level layout?
+                          ├─ YES → TEMPLATE (MainLayout, CheckoutLayout)
+                          └─ NO → PAGE (app/page.tsx)
+```
+
+### Creating a New Component Checklist
+
+- [ ] Determine component level (Atom/Molecule/Organism/Template)
+- [ ] Create directory: `components/[level]/[category]/`
+- [ ] Create `ComponentName.tsx` with TypeScript
+- [ ] Create `ComponentName.types.ts` with Props interface
+- [ ] Add to `index.ts` barrel export in that level
+- [ ] Test responsive design (mobile/tablet/desktop)
+- [ ] Update markdown documentation
+- [ ] Run `npm run format` and `npm run lint`
+- [ ] Commit with conventional message
+
+### Common File Locations
+
+- **Atoms:** `components/atoms/[category]/ComponentName.tsx`
+- **Molecules:** `components/molecules/[category]/ComponentName.tsx`
+- **Organisms:** `components/organisms/[section-type]/ComponentName.tsx`
+- **Templates:** `components/templates/[layout-type]/TemplateName.tsx`
+- **Pages:** `app/[route]/page.tsx`
+- **Layouts (root):** `layouts/header.tsx`, `layouts/footer.tsx`
+- **Contexts:** `lib/auth-context.tsx`, `lib/cart-context.tsx`
+- **Types:** `lib/types.ts`
+- **Constants:** `lib/constants.ts`
+
+### Import Patterns
+
+```tsx
+// Atoms
+import Button from "@/components/atoms/buttons/Button";
+import { Button } from "@/components/atoms"; // via barrel
+
+// Molecules
+import ProductCard from "@/components/molecules/cards/ProductCard";
+import { ProductCard } from "@/components/molecules";
+
+// Organisms
+import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
+import { ProductGrid } from "@/components/organisms";
+
+// Templates
+import MainLayout from "@/components/templates/main-layout/MainLayout";
+import { MainLayout } from "@/components/templates";
+
+// Contexts
+import { useAuth } from "@/lib/auth-context";
+import { useCart } from "@/lib/cart-context";
+```
+
+### CSS Variables (from `globals.css`)
+
+```css
+/* Colors */
+--color-primary: main brand color --color-primary-dark: darker shade
+  --color-accent: secondary color --color-bg-main: main background
+  --color-bg-card: card background --color-bg-sidebar: sidebar background
+  --color-text-primary: main text color --color-text-secondary: secondary text
+  --color-text-muted: gray/muted text --color-border: border color
+  --color-border-light: light border --color-shadow-sm: small shadow
+  --color-shadow-md: medium shadow /* Spacing */ --spacing-header-height: 72px;
+```
+
+### Useful Commands
+
+```bash
+# Development
+npm run dev              # Start dev server
+
+# Code quality
+npm run lint            # Run ESLint
+npm run format          # Format code with Prettier
+
+# Build & Deploy
+npm run build           # Build for production
+npm start               # Start production server
+
+# Release
+npm run release         # Semantic release (auto-version + changelog)
+```
+
+### Common Patterns
+
+**Filtering products by category (in Organism):**
+
+```tsx
+const filtered = MOCK_PRODUCTS.filter(
+  (p) => activeCategory === "all" || p.category === activeCategory,
+);
+```
+
+**Using Atoms in Molecules:**
+
+```tsx
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+
+export default function Card() {
+  return (
+    <div>
+      <Text variant="body1">Product Name</Text>
+      <Button onClick={handleClick}>Add</Button>
+    </div>
+  );
+}
+```
+
+**Using Organisms in Templates:**
+
+```tsx
+import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
+
+export default function MainLayout({ children }) {
+  return (
+    <div>
+      <header>Header</header>
+      <ProductGrid />
+      {children}
+    </div>
+  );
+}
+```
+
+**Responsive classes (all levels):**
+
+```tsx
+// Mobile-first: base style applies to all, sm:/md:/lg: apply at breakpoints
+className = "w-full sm:w-1/2 md:w-1/3 p-4 md:p-6 hidden md:block";
+```

+# ATOMIC DESIGN STRUCTURE GUIDE
+
+## Overview
+
+Project sử dụng **Atomic Design Pattern** để tổ chức UI components theo 5 cấp
+độ:
+
+1. **Atoms** - Khối xây dựng cơ bản, không thể chia nhỏ hơn
+2. **Molecules** - Nhóm atoms đơn giản hoạt động cùng nhau
+3. **Organisms** - Khu vực UI phức tạp, riêng biệt
+4. **Templates** - Bố cục cấp trang, cấu trúc nội dung
+5. **Pages** - Các phiên bản cụ thể với dữ liệu thật
+
+---
+
+## 1) ATOMS (`components/atoms/`)
+
+**Mục đích:** Khối xây dựng cơ bản, tái sử dụng cao, không phụ thuộc logic phức
+tạp.
+
+Không có context/hooks logic phức tạp, chỉ nhận props từ parent.
+
+### Cấu trúc thư mục

+```
+
+### Ví dụ Atoms
+
+**Button.tsx:**
+
+```tsx
+import { ButtonHTMLAttributes } from "react";
+
+import type { ButtonProps } from "./Button.types";
+
+export default function Button({
+  variant = "primary",
+  size = "md",
+  disabled = false,
+  children,
+  className = "",
+  ...props
+}: ButtonProps) {
+  const baseStyles =
+    "font-semibold rounded-lg transition-colors disabled:opacity-50";
+  const variants = {
+    primary:
+      "bg-[color:var(--color-primary)] text-white hover:bg-[color:var(--color-primary-dark)]",
+    secondary: "bg-gray-200 text-gray-800 hover:bg-gray-300",
+    danger: "bg-red-500 text-white hover:bg-red-600",
+  };
+  const sizes = {
+    sm: "px-3 py-1 text-sm",
+    md: "px-4 py-2 text-base",
+    lg: "px-6 py-3 text-lg",
+  };
+
+  return (
+    <button
+      className={`${baseStyles} ${variants[variant]} ${sizes[size]} ${className}`}
+      disabled={disabled}
+      {...props}
+    >
+      {children}
+    </button>
+  );
+}
+```
+
+**Button.types.ts:**
+
+```tsx
+import { ButtonHTMLAttributes } from "react";
+
+export interface ButtonProps extends ButtonHTMLAttributes<HTMLButtonElement> {
+  variant?: "primary" | "secondary" | "danger";
+  size?: "sm" | "md" | "lg";
+  disabled?: boolean;
+  children: React.ReactNode;
+  className?: string;
+}
+```
+
+---
+
+## 2) MOLECULES (`components/molecules/`)
+
+**Mục đích:** Nhóm atoms tạo thành những UI unit nhỏ, tái sử dụng, có logic đơn
+giản.
+
+Có thể sử dụng `useState`, nhưng logic chủ yếu nằm ở parent component.

+
+### Ví dụ Molecules
+
+**ProductCard.tsx:**
+
+```tsx
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+import Image from "next/image";
+
+import type { ProductCardProps } from "./Card.types";

+        />
+      </div>
+      <Text variant="body1" className="font-semibold">

+    </div>
+  );
+}
+```
+
+---
+
+## 3) ORGANISMS (`components/organisms/`)
+
+**Mục đích:** Khu vực UI phức tạp, độc lập, có logic riêng.
+
+Kết hợp multiple molecules/atoms, có thể sử dụng contexts (useAuth, useCart,
+etc.), state phức tạp.
+

+### Ví dụ Organisms
+
+**ProductGrid.tsx:**
+
+```tsx
+"use client";
+
+import ProductCard from "@/components/molecules/cards/ProductCard";
+import { useCart } from "@/lib/cart-context";
+import { MOCK_PRODUCTS } from "@/lib/constants";
+import { useMenu } from "@/lib/menu-context";

+import type { ProductGridProps } from "./ProductGrid.types";
+
+export default function ProductGrid({ searchQuery = "" }: ProductGridProps) {
+  const { activeCategory } = useMenu();

+        />
+      ))}
+    </div>
+  );
+}
+```
+
+---
+
+## 4) TEMPLATES (`components/templates/`)
+
+**Mục đích:** Bố cục cấp trang, cấu trúc nội dung, không có data cụ thể.
+
+Chứa layout và structure của page, nhưng data được truyền từ page component.

+### Ví dụ Templates
+
+**MainLayout.tsx:**
+
+```tsx
+import Navbar from "@/components/organisms/navigation/Navbar";
+import Footer from "@/layouts/footer";
+import Header from "@/layouts/header";
+
+import type { MainLayoutProps } from "./MainLayout.types";
+
+export default function MainLayout({ children }: MainLayoutProps) {
+  return (
+    <div className="flex min-h-screen flex-col">
+      <Header />
+      <div className="flex flex-1">
+        {/* Sidebar - ẩn trên mobile */}
+        <nav className="hidden w-64 border-r border-[color:var(--color-border)] bg-[color:var(--color-bg-sidebar)] md:block">
+          <Navbar />
+        </nav>
+        {/* Main content */}
+        <main className="flex-1 p-4 md:p-6">{children}</main>
+      </div>
+      <Footer />
+    </div>
+  );
+}
+```
+
+---
+
+## 5) PAGES (`app/*/page.tsx`)
+
+**Mục đích:** Các phiên bản cụ thể với dữ liệu thật, logic cấp trang.
+
+Server/client components sử dụng templates, organisms, nhận data từ API/context.
+
+### Ví dụ Pages
+
+**app/(main)/page.tsx:**
+
+```tsx
+"use client";
+
+import FeaturedSection from "@/components/organisms/featured-section/FeaturedSection";
+import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
+import MainLayout from "@/components/templates/main-layout/MainLayout";
+import { useState } from "react";
+
+export default function MainPage() {
+  const [searchQuery, setSearchQuery] = useState("");
+
+  return (
+    <MainLayout>
+      <FeaturedSection />
+      <div className="mt-8">
+        <ProductGrid searchQuery={searchQuery} />
+      </div>
+    </MainLayout>
+  );
+}

+## 7) Migration Guide (Old → New)
+
+### Old Structure → New Structure Mapping
+
+| Old File          | New Location                       | Type     |
+| ----------------- | ---------------------------------- | -------- |
+| `CartProduct.tsx` | `molecules/cards/ProductCard.tsx`  | Molecule |
+| `Navbar.tsx`      | `organisms/navigation/Navbar.tsx`  | Organism |
+| `CartFab.tsx`     | `organisms/cart/CartFab.tsx`       | Organism |
+| `ReviewModal.tsx` | `organisms/modals/ReviewModal.tsx` | Organism |
+
+### Migration Steps
+
+1. Create new directory structure under `components/`
+2. Move existing components to appropriate levels (atoms → molecules →
+   organisms)
+3. Extract shared styles/logic into atoms
+4. Update imports in `app/` pages
+5. Test responsiveness at each breakpoint
+6. Update `COMPONENTS.md` with new structure
+
+---
+
+## 8) Best Practices
+
+### Atoms Development
+
+- ✅ Reusable across entire project
+- ✅ No business logic
+- ✅ No context/hooks (useAuth, useCart)
+- ✅ Pure props-based
+- ✅ Full TypeScript typing
+- ❌ No "use client" needed (unless interactive, e.g., Button)
+
+### Molecules Development
+
+- ✅ Combines multiple atoms
+- ✅ Simple state (open/close, hover state)
+- ✅ No complex business logic
+- ✅ Can use useState for UI state
+- ✅ Reusable in multiple contexts
+- ❌ No global state (useAuth, useCart)
+
+### Organisms Development
+
+- ✅ Complex UI sections
+- ✅ Can use contexts (useAuth, useCart, useMenu)
+- ✅ Business logic
+- ✅ Always "use client"
+- ✅ Filter, sort, complex interactions
+- ❌ Not reusable across different page types
+
+### Templates Development
+
+- ✅ Page layout structure
+- ✅ Composition of organisms + layout
+- ✅ No data fetching/business logic
+- ✅ Children prop pattern
+- ✅ Props for customization
+- ❌ No hardcoded data
+
+### Pages Development
+
+- ✅ Specific page implementations
+- ✅ Route-specific logic
+- ✅ Data integration
+- ✅ Context usage at page level
+- ✅ State management orchestration
+- ❌ No UI component definitions (use organisms)
+

+
+## 9) Import Patterns
+
+### Atoms
+
+```tsx
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+```
+
+### Molecules
+
+```tsx
+import ProductCard from "@/components/molecules/cards/ProductCard";
+import FormField from "@/components/molecules/form-groups/FormField";
+```
+
+### Organisms
+
+```tsx
+import LoginForm from "@/components/organisms/forms/LoginForm";
+import ProductGrid from "@/components/organisms/product-grid/ProductGrid";
+```
+
+### Templates
+
+```tsx
+import MainLayout from "@/components/templates/main-layout/MainLayout";
+```
+
+### Barrel Exports
+
+```tsx
+// Usage
+import { Button, Text } from "@/components/atoms";
+
+// components/atoms/index.ts
+export { default as Button } from "./buttons/Button";
+export { default as Text } from "./typography/Text";
+export * from "./buttons/Button.types";
+```
+
+---
+
+## 10) Common Patterns
+
+### Creating a New Atom
+
+```tsx
+// atoms/buttons/NewButton.tsx
+export default function NewButton({ variant, ...props }: Props) {
+  return <button className={styles[variant]} {...props} />;
+}
+
+// atoms/buttons/NewButton.types.ts
+export interface Props extends ButtonHTMLAttributes<HTMLButtonElement> {
+  variant: "type1" | "type2";
+}
+```
+
+### Creating a New Molecule
+
+```tsx
+// molecules/cards/NewCard.tsx
+export default function NewCard({ item, onAction }: Props) {
+  const [hover, setHover] = useState(false);
+  return (
+    <div onMouseEnter={() => setHover(true)}>{/* atoms composition */}</div>
+  );
+}
+```
+
+### Creating a New Organism
+
+```tsx
+// organisms/sections/NewSection.tsx
+"use client";
+
+import ProductCard from "@/components/molecules/cards/ProductCard";
+import { useAuth } from "@/lib/auth-context";
+
+export default function NewSection() {
+  const { user } = useAuth();
+  // business logic, filtering, etc.
+  return <section>{/* molecules composition + logic */}</section>;
+}
+```
+
+### Creating a New Template
+
+```tsx
+// templates/layouts/NewTemplate.tsx
+export default function NewTemplate({ children, header }: Props) {
+  return (
+    <div className="layout">
+      <header>{header}</header>
+      <main>{children}</main>
+    </div>
+  );
+}
+```
+
+---
+
+## 11) Testing & Documentation
+
+### For Each Component Level
+
+#### Atoms
+
+- Unit test: Props validation, styling
+- Storybook: All variants, all states
+- Doc: Props interface, usage examples
+
+#### Molecules
+
+- Integration test: Atoms composition
+- Storybook: Different molecule states
+- Doc: Props, behavior, dependencies
+
+#### Organisms
+
+- Integration test: With contexts mocked
+- E2E: User interactions
+- Doc: Logic flow, API integration points
+
+#### Templates
+
+- Layout test: Responsive grid layouts
+- Visual: Desktop/tablet/mobile
+- Doc: Layout structure, breakpoints
+
+#### Pages
+
+- E2E test: Full user flows
+- Performance: Metrics
+- Doc: Route, data flow, features
+
+---
+
+## 12) Performance Optimization
+
+### Code Splitting
+
+- Atoms: Always bundled (small, frequently used)
+- Molecules: Bundled by page/feature
+- Organisms: Use `dynamic()` for heavy sections
+- Templates: Bundled by layout type
+- Pages: Automatic splitting by Next.js
+
+### Lazy Loading Example
+
+```tsx
+import dynamic from "next/dynamic";
+
+const ReviewModal = dynamic(
+  () => import("@/components/organisms/modals/ReviewModal"),
+  { loading: () => <Spinner /> },
+);
+```
+
+### Image Optimization
+
+- Use Next.js `Image` component (atoms/molecules)
+- Optimize with `priority` for above-fold
+- Use responsive sizes: `sizes="(max-width: 640px) 100vw, 50vw"`
+
+---
+
+## 13) Accessibility
+
+### All Levels
+
+- Semantic HTML: `<button>`, `<a>`, `<form>`, `<nav>`
+- ARIA attributes: `aria-label`, `aria-expanded`, `role`
+- Keyboard navigation: Tab order, focus visible
+- Color contrast: WCAG AA minimum
+- Alt text: All images have meaningful `alt`
+
+### Example
+
+```tsx
+<button
+  aria-label="Add to cart"
+  className="focus:ring-2 focus:ring-blue-500 focus:ring-offset-2"
+>
+  <CartIcon aria-hidden="true" />
+  Add to Cart
+</button>
+```
+
+---
+
+## 14) Version Control & Documentation
+
+### File Format
+
+```

+
+## 💡 Design Decisions
+
+### Why Barrel Exports?
+```tsx
+// ❌ Bad: Scattered imports
+import Button from "@/components/atoms/buttons/Button";
+import Text from "@/components/atoms/typography/Text";
+
+// ✅ Good: Single clean import
+import { Button, Text } from "@/components/atoms";
+```
+
+### Why TypeScript Types in Separate Files?
+- Clear separation of concerns
+- Easier to maintain interfaces
+- Reusable types across modules
+- Better for large components
+
+### Why CSS Variables?
+- Single point for theme changes
+- Easy dark mode switching
+- Consistent across all atoms
+- No inline style duplication
+

 ## Ghi Chú Phát Triển
 
-- Trang chủ (app/page.tsx) là điểm vào chính của User Page
-- Design tokens định nghĩa trong app/globals.css dưới dạng CSS custom properties
-- Mock data nằm trong lib/constants.ts - thay bằng API calls khi backend sẵn
-  sàng
-- Dark mode: biến CSS đã chuẩn bị sẵn trong globals.css nhưng chưa kích hoạt
-- Ảnh sản phẩm: thêm ảnh thực vào public/imgs/products/
-- Xem WORKFLOW.md để hiểu kiến trúc tổng thể và quy trình mở rộng dự án
+### Điểm Vào Chính
+
+- **Trang Chủ (User):** `app/(main)/page.tsx` - Duyệt thực đơn
+- **Trang Khám Phá:** `app/(feed)/feed/page.tsx` - Khám phá quán
+- **Đăng Nhập:** `app/(main)/login/page.tsx`
+- **Đăng Ký:** `app/(main)/register/page.tsx`
+- **Thanh Toán:** `app/(main)/payment/page.tsx`
+- **Manager Dashboard:** `app/(manager)/manager/page.tsx`
+- **Phân Tích Tài Chính:** `app/(manager)/manager/analytics/page.tsx`
+
+### Tài Khoản Demo
+
+| Loại tài khoản | Tên đăng nhập  | Mật khẩu       |
+| -------------- | -------------- | -------------- |
+| Manager        | admin          | admin          |
+| Staff          | Nguyễn Văn An  | Nguyễn Văn An  |
+| Customer       | 0987654321     | user1          |
+
+### Design & Styling
+
+- Design tokens (CSS variables) định nghĩa trong `app/globals.css`
+- Tailwind CSS v4 + custom properties cho consistent color/spacing
+- Dark mode: biến CSS đã chuẩn bị sẵn nhưng chưa kích hoạt
+- FontAwesome icons từ CDN
+
+### Kiến Trúc Component (Atomic Design)
+
+Dự án tuân theo **Atomic Design** pattern — chi tiết tại `Atomic.md`:
+
+- **Atoms** - Nguyên tố cơ bản: Button, Input, Badge, Text, Heading, Divider
+- **Molecules** - Nhóm atoms: ProductCard, ShopCard, SearchBar, PaymentSummaryCard
+- **Organisms** - Phần UI phức tạp: CategorySidebar, CartFab, ProductGrid, ShopGrid, ReviewModal, analytics charts, manager tabs/modals
+- **Templates** - Bố cục trang: MainLayout, AuthLayout, FeedLayout, ManagerLayout
+
+### Data & Integration
+
+- Mock data nằm trong `lib/constants.ts`
+- Context providers trong `app/providers.tsx`: AuthProvider, MenuProvider, CartProvider
+- ManagerProvider được thêm bởi `app/(manager)/layout.tsx`
+- Thay bằng API calls khi backend sẵn sàng
+- Ảnh sản phẩm: thêm vào `public/imgs/products/`
+
+### Tài Liệu Chi Tiết
+
+- **WORKFLOW.md** - Kiến trúc tổng thể, data flow, quy trình phát triển
+- **Atomic.md** - Cấu trúc Atomic Design và quy ước component
+- **APP.md** - Chi tiết các routes, layouts, pages
+- **COMPONENTS.md** - Tài liệu từng component (Atomic Design)
+- **LAYOUTS.md** - Header, Footer, responsive behavior
+- **LIB.md** - Constants, Types, Contexts
+- **AGENTS.md** - Hướng dẫn cho AI agents làm việc với codebase

+```
+
+#### Data Source
+
+- MOCK_SHOPS from lib/constants.ts
+
+---
+
+## CSS & Styling
+
+### Global Styles (app/globals.css)
+
+**Description:** Root CSS file. Imports Tailwind CSS, defines design tokens (CSS
+variables), and global styles.
+
+### Design Tokens (CSS Variables)
+
+Defined at `:root` for light mode, with dark mode variants:
+
+#### Colors
+
+- `--color-primary` - Main brand color (brown)
+- `--color-primary-dark` - Darker shade for hover
+- `--color-accent` - Secondary accent color
+- `--color-bg-*` - Background colors (main, card, sidebar)
+- `--color-border-*` - Border colors
+- `--color-text-*` - Text colors (primary, secondary, muted)
+- `--color-shadow-*` - Shadow colors (sm, md)
+
+#### Spacing
+
+- `--spacing-header-height` - Header component height
+- Standard Tailwind spacing (via Tailwind)
+
+#### Typography
+
+- Font stack defined via Google Fonts (Geist)
+
+### Tailwind Config Integration
+
+- v4 with custom properties support
+- Extends with CSS variables
+- Dark mode: CSS variable override
+
+---
+
+## Key Concepts
+
+### Route Groups
+
+- `(main)` and `(feed)` are route groups (don't appear in URL)
+- Allow different layouts/providers per route group
+- Used for organization and flexibility
+
+### SSR vs Client Components
+
+- Most pages are "use client" (need interactivity)
+- Context providers must be client components
+- Layout.tsx can be server component
+
+### Responsive Design
+
+- Breakpoints: sm (640px), md (768px), lg (1024px), xl (1280px), 2xl (1536px)
+- Sidebar width affects grid columns
+- Mobile: vertical layout, collapsed sidebar
+- Desktop: horizontal layout, expanded sidebar
+
+### Navigation
+
+- Internal links use `next/link`
+- useRouter() for programmatic navigation
+- Auth redirects after login/register
+
+---
+
+## Development Workflow
+
+### Adding a New Page
+
+1. Create file under appropriate route group: `app/(main)/new-feature/page.tsx`
+2. Make it a client component if it needs interactivity: `"use client"`
+3. Use context hooks as needed (useAuth, useCart, useMenu)
+4. Export default component
+5. Add to documentation
+
+### Adding a New Route Group
+
+1. Create directory: `app/(group-name)/`
+2. Create `layout.tsx` if custom layout needed
+3. Add pages under this group
+4. Update codebase understanding
+
+### Styling Pages
+
+- Use Tailwind classes + CSS variables
+- Reference design tokens for consistency
+- Follow responsive patterns from existing pages
+
+---
+
+## (manager) Route Group
+
+### Layout (app/(manager)/layout.tsx)
+
+**Description:** Layout for manager routes. Guards access — redirects
+non-managers to `/`. Wraps children in `ManagerProvider`.
+
+---
+
+### Manager Dashboard (app/(manager)/manager/page.tsx)
+
+**Route:** `/manager` **Type:** Client component **Description:** Full menu
+management interface for the shop owner.
+
+#### Key Features
+
+- **Sidebar (desktop):** Brand, tab navigation (Thực đơn / Combo / Danh mục),
+  link to Financial Analytics, user info, logout
+- **Top bar:** Page title, mobile tab switcher, analytics shortcut button
+- **Tabs:** Products, Combos, Categories — each with CRUD modals
+- **Analytics link:** `fa-chart-line` button → `/manager/analytics`
+
+---
+
+### Financial Analytics (app/(manager)/manager/analytics/page.tsx)
+
+**Route:** `/manager/analytics` **Type:** Client component **Description:**
+Financial analytics and reporting dashboard for the shop manager.
+
+#### Key Features
+
+- **Summary cards:** Total revenue, orders, profit, average order value — each
+  with period-over-period comparison %
+- **Period selector:** Day / Week / Month / Year — switches revenue dataset
+- **Chart switcher:** Line chart (trend), Bar chart (current vs previous half),
+  Pie chart (revenue by category)
+- **SVG charts:** Pure SVG, no external library — hover tooltips stay inside
+  viewBox (auto-flip above/below for line points & bar tops), interactive
+  dots/slices
+- **Top 5 products:** Horizontal bar ranking filtered by category
+- **Product detail table:** All 18 products sortable by units sold, revenue,
+  profit, margin
+- **Summary row:** Totals for filtered data (revenue, profit, volume, avg
+  margin)
+- **Category filter:** Dropdown to filter both top-5 and detail table
+
+#### Data Sources
+
+- `MOCK_REVENUE_DAILY/WEEKLY/MONTHLY/YEARLY` from `lib/constants.ts`
+- `MOCK_PRODUCT_SALES` from `lib/constants.ts`
+- `MENU_CATEGORIES` for category labels
+
+#### State Management
+
+```tsx
+period: AnalyticsPeriod; // "day" | "week" | "month" | "year"
+activeChart: "line" | "bar" | "pie";
+categoryFilter: string; // category id or "all"
+```
+
+---
+
+## Future Enhancements
+
+- [x] Payment page implementation
+- [x] Customer review modal (ReviewModal) with 5-star rating + textarea
+- [x] Manager dashboard (menu management)
+- [x] Financial Analytics dashboard (charts, profit analysis)
+- [ ] Order history/tracking page
+- [ ] User profile page
+- [ ] Cart checkout flow
+- [ ] Real backend API integration

+# Atoms Components Library
+
+**Status:** ✅ Phase 1 Implementation Complete
+**Created:** 2026-04-03
+**Foundation:** Atomic Design Pattern
+
+---
+
+## 📚 Overview
+
+Atoms are the basic building blocks of your UI. They are small, focused, reusable components that have no dependencies on other components (except potentially other atoms).
+
+**Key Principles:**
+- ✅ No business logic
+- ✅ No context/hooks (useAuth, useCart, etc.)
+- ✅ Pure props-based
+- ✅ Full TypeScript typing
+- ✅ CSS variables for theming
+- ✅ Accessible by default
+
+---

+
+#### **PriceBadge.tsx**
+Specialized badge for displaying formatted prices.
+
+**Props:**
+- `price` - number
+- `currency` - string (default: "VND")
+- All standard HTML span attributes
+
+**Usage:**
+```tsx
+import { PriceBadge } from "@/components/atoms";
+
+<PriceBadge price={50000} />
+<PriceBadge price={99.99} currency="USD" />
+```
+
+**Output:**
+- VND: "50.000 ₫"
+- USD: "$99.99"
+
+---
+
+### Dividers (`dividers/`)
+
+#### **Divider.tsx**
+Visual separator element.
+
+**Props:**
+- `orientation` - "horizontal" | "vertical" (default: "horizontal")
+- All standard HTML hr attributes
+
+**Usage:**
+```tsx
+import { Divider } from "@/components/atoms";
+
+<Divider /> {/* Horizontal line */}
+<Divider orientation="vertical" className="h-12" />
+```
+
+---
+
+## 🎨 Theming
+
+All atoms use CSS variables for consistent theming:
+
+```css
+/* Colors */
+--color-primary
+--color-primary-dark
+--color-accent
+--color-accent-light
+--color-bg-card
+--color-text-primary
+--color-text-secondary
+--color-text-muted
+--color-border
+--color-border-light
+--color-shadow-sm
+--color-shadow-md
+```
+
+Change one variable in `globals.css` to update all atoms across the app.
+
+---
+
+## 🔄 Import Patterns
+
+### Individual Imports
+```tsx
+import { Button } from "@/components/atoms/buttons";
+import { TextInput, SearchInput } from "@/components/atoms/inputs";
+import { Heading, Text, Caption } from "@/components/atoms/typography";
+import { Badge, PriceBadge } from "@/components/atoms/badges";
+import { Divider } from "@/components/atoms/dividers";
+```
+
+### Barrel Exports (Recommended)
+```tsx
+import {
+  Button,
+  IconButton,
+  TextInput,
+  SearchInput,
+  Textarea,
+  Heading,
+  Text,
+  Caption,
+  Badge,
+  PriceBadge,
+  Divider,
+} from "@/components/atoms";
+```
+
+### Type Imports
+```tsx
+import type { ButtonProps, TextInputProps, HeadingProps } from "@/components/atoms";
+```
+
+---
+
+## ✅ Usage Examples
+
+### Form Field
+```tsx
+<div className="space-y-4">
+  <TextInput
+    label="Name"
+    placeholder="Enter your name"
+    type="text"
+  />
+  <TextInput
+    label="Email"
+    placeholder="user@example.com"
+    type="email"
+    error={emailError}
+  />
+  <Button type="submit">Submit</Button>
+</div>
+```
+
+### Product Card
+```tsx
+<div className="rounded-lg border p-4">
+  <Heading level={3}>Product Name</Heading>
+  <Text variant="body2">Product description</Text>
+  <div className="flex items-center justify-between mt-4">
+    <PriceBadge price={50000} />
+    <Button icon="fa-cart-plus">Add to Cart</Button>
+  </div>
+</div>
+```
+
+### Rating Display
+```tsx
+<div>
+  <Heading level={4}>Reviews</Heading>
+  <Text variant="body1">⭐⭐⭐⭐⭐ 4.5/5</Text>
+  <Caption>Based on 128 reviews</Caption>
+</div>
+```
+
+---
+
+## 🧪 Testing Atoms
+
+### Props Validation
+```tsx
+// ✅ Valid
+<Button variant="primary" size="sm">Click</Button>
+
+// ❌ Invalid (TypeScript will catch)
+<Button variant="invalid">Click</Button>
+<Button size={10}>Click</Button>
+```
+
+### Accessibility
+All atoms include:
+- Semantic HTML
+- ARIA labels where appropriate
+- Keyboard navigation support
+- Focus visible states
+- Color contrast compliance
+

+
+## 🚀 Next Steps
+
+Once atoms are comfortable, the next phase is creating **Molecules** - combinations of atoms:
+
+- **ProductCard** - Image + Text + Badge + Button
+- **FormField** - Label + Input + Error Text
+- **SearchBar** - SearchInput + Button
+- **RatingInput** - Interactive 5-star rating
+- **PriceTag** - Price display with formatting
+- And more...
+
+See `OPTIMIZATION_PLAN.md` for the full roadmap.
+
+---
+
+## 📝 Notes
+
+- All atoms use TypeScript for type safety
+- No business logic in atoms - they're purely presentational
+- Components are optimized for reusability
+- Styling uses Tailwind + CSS variables for consistency
+- Accessibility is built-in by default
+
