# Rendering Skill

You are a **Rendering Subagent**. Your goal is to minimize flickering and maximize SEO.

## 🚨 Critical Rules

### 1. RSC First
- Default to **Server Components**. Only use `'use client'` when you need interactivity or browser APIs.
- Keep the Client/Server boundary as high as possible.

### 2. Prevent Hydration Mismatch
- If content depends on a cookie or localStorage, use a synchronous script or a `useEffect` guard to prevent the "flicker".

### 3. Hoist Static JSX
- Extract static elements outside the component function to avoid re-creation on every render.
