+## Setup (run in order)
+
+### 1. Next.js
+
+- **Command:** `npx create-next-app@latest . --yes` (run from repo root; may need `required_permissions: ["all"]` in sandbox)
+- **Result:** TypeScript, ESLint, Tailwind v4, App Router, Turbopack, `@/*` → `./*`, no `src/`. App in `app/`, static in `public/`.
+- **Scripts:** `dev` | `build` | `start` | `lint`. Dev server: http://localhost:3000.
+- **Routes:** `app/layout.tsx`, `app/page.tsx`. Imports: `@/` = project root.
+- **Ref:** [Next.js App Router Installation](https://nextjs.org/docs/app/getting-started/installation) — verify against current docs.
+
+### 2. shadcn/ui
+
+- **Requires:** Next.js + Tailwind v4 + App Router + `@/*`, no `src/`.
+- **Init:** `npx shadcn@latest init -t next -y -b zinc --no-src-dir`
+- **Add components:** `npx shadcn@latest add button -y` (e.g. `card`, `dialog`, `input`; `-o` overwrites).
+- **Output:** `components.json`, `lib/utils.ts` (cn), `app/globals.css` (tw-animate, shadcn/tailwind.css, CSS vars). UI in `components/ui/<name>.tsx`. Import: `import { Button } from "@/components/ui/button"`.
+- **Ref:** [shadcn Next.js](https://ui.shadcn.com/docs/installation/next) | [CLI](https://ui.shadcn.com/docs/cli).
+
+### 3. Framer Motion
+
+```bash
+npm i framer-motion
+```
+
+- **Ref:** [Framer Motion](https://motion.dev/)
+
+### 4. AI SDK (optional)
+
+Note: Install only when create a conversational user interface for your chatbot application. It enables the streaming of chat messagesyou need to stream responses from the backend using useChat().
+
+- **When:** Add this step only if the app needs a chat UI (e.g. query-agent or chatbot flows).
+- **Stack:** Use the [Vercel AI SDK](https://ai-sdk.dev/docs/introduction) (`ai` + `@ai-sdk/*`). Use `useChat` and SDK UI primitives for the chat view.
+- **Ref:** [AI SDK – useChat](https://ai-sdk.dev/docs/reference/ai-sdk-ui/use-chat) | [Next.js App Router setup](https://ai-sdk.dev/docs/getting-started/nextjs-app-router) — follow current docs for install and wiring.
+
+```bash
+npm i ai @ai-sdk/react zod
+```
+
+### 5. Environment
+
+**Required:**
+
+```bash
+NEXT_PUBLIC_BACKEND_HOST="localhost:8000"
+```
+
+Use the actual backend host when not local.
+
+---
+
+## Rules (must follow)
+
+### Stack and structure
+
+- **UI:** Use **shadcn components only** for layout and interactive elements (buttons, cards, inputs, dialogs, etc.). Do not add another UI library.
+- **Architecture:** **SPA** — one main page, update main view in place. Avoid full-page navigations unless necessary.
+- **Icons:** Use **react-icons** only; prefer one set (e.g. `react-icons/fa` or `react-icons/hi`) for consistency.
+- **Animation:** Use **Framer Motion** only. Do not add another animation library.
+
+### Visual style
+
+- **Goal:** Minimal, sleek, clean. No clutter, heavy borders, or noisy backgrounds.
+- **Aesthetic:** “Liquid glass” — frosted, translucent; soft blur; light borders and shadows; depth without heaviness. Use `backdrop-blur`, semi-transparent fills, subtle gradients where they support this.
+
+### Motion
+
+- **Style:** Subtle, springy, purposeful (fade in, hover, enter/exit). Prefer spring physics over linear/ease-out.
+
+### Layout
+
+1. **Left:** shadcn **Sidebar** component.
+2. **Right:** Main content area.
+3. **Navigation:** One sidebar button per backend feature (e.g. data explorer, chat). Click switches the main view only.
+
+### Responsiveness
+
+- Layout and components must work on small and large screens.
