+Next.js 16 (App Router), React 19, TypeScript strict, Tailwind v4, shadcn/ui, base-ui.
+
+Key points:
+- **All pages** are `"use client"` — the dashboard is fully client-rendered
+- **API client** at `src/lib/api/` — fetch-based, covers all 30+ backend endpoints
+- **WebSocket** at `src/lib/ws/` — auto-reconnecting client with typed event subscriptions
+- **Static export**: `output: "export"` in next.config.ts, served via nginx
+- **No authentication**: all endpoints are public

+# Bete Frontend
 
-## Getting Started
+Next.js 16 (React 19) dashboard untuk Discord Moderation Watcher.

+**Stack:** Next.js 16 (App Router, static export), React 19, TypeScript strict, Tailwind v4, shadcn/ui, base-ui, lucide-react.
+
+## Dev
 
 ```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+bun run dev        # next dev — port 3000
+bun run build      # next build — static export ke out/
+bun run lint       # Biome check
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+## Architecture
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
