+## 1. Technical Foundation
+
+รากฐานทางเทคนิคที่ขับเคลื่อนระบบ เพื่อให้ได้ประสิทธิภาพและความเสถียรสูงสุด
 
 ### 1.1 Tech Stack
 
-- **Core:** [Nuxt 3](https://nuxt.com) (v`^3.11.2`), TypeScript `^5.4.5`
+- **Framework:** Nuxt 3 (Vue 3, Vite, SSR/SPA Hybrid)
-- **UI Framework:** Quasar Framework `^2.15.2` (via `nuxt-quasar-ui ^3.0.0`)
+- **UI System:** Quasar Framework + Tailwind CSS (Utility-first)
-- **Styling:** Tailwind CSS `^6.12.0` (Utility) + Vanilla CSS Variables (Theming/Dark Mode)
+- **Typography:** Google Fonts (**Prompt** เป็น Font หลักเพื่อความทันสมัยและอ่านง่าย)
-- **State Management:** `ref`/`reactive` (Local) + `useState` (Global/Shared State)
+- **Multilingual:** `@nuxtjs/i18n` (รองรับ JSON-based locales ภาษาไทยและอังกฤษ)
-- **Localization:** `@nuxtjs/i18n` (Supports JSON locales in `i18n/locales/`)
+- **Programming:** TypeScript (Strict Type Checking)
-- **Media Control:** `useMediaPrefs` (Command Pattern for global volume/mute state)
 
-### 1.2 Core Systems & Security
+### 1.2 Security & Authentication
 
-- **Authentication:**
+- **Token Management:** ใช้ JWT (Access & Refresh Tokens) จัดเก็บผ่าน `useCookie`  
-  - ใช้ **JWT** (Access Token 1 วัน, Refresh Token 7 วัน)
+  โดยตั้งค่าความปลอดภัยระดับ **HTTP-only** และ **SameSite**
-  - เก็บ Token ใน `useCookie` (Secure, SameSite)
+- **Middleware:** `auth.ts` ตรวจสอบสิทธิ์การเข้าถึงหน้า Dashboard และ Classroom แบบ Real-time
-  - Middleware (`middleware/auth.ts`) ป้องกัน Route ตามสถานะ
+- **Persistence:** ระบบ Remember Me (จดจำอีเมล) ใช้ `localStorage` แยกส่วนจาก Session  
-  - **Remember Me:** ระบบจดจำอีเมลลงใน `localStorage` (จำแยกจาก session, ไม่ถูกลบเมื่อ Logout)
+  เพื่อความปลอดภัยและสะดวกสำหรับผู้ใช้
-- **API Handling:**
-  - ใช้ `runtimeConfig.public.apiBase` เชื่องโยง Backend
-  - Auto-attach Bearer Token ใน `useAuth` และ `useCourse`
-- **Performance:**
-  - **Hybrid Progress Saving:** บันทึกเวลาเรียนลง LocalStorage (ถี่) และ Server (Throttle 15s) เพื่อความแม่นยำสูงสุด
-  - **Caching:** ใช้ `useState` จำข้อมูล Profile และ Categories ลด request
-  - **Code Quality:** ลบ Log, Dead logic และ Redundant comments ทั่วทั้งโปรเจกต์ (Clean Code Phase)
