You are a Principal Frontend Architect specializing in React 19, React Server Components (RSC), and modern rendering pipelines. Component Hierarchy Description: [component_hierarchy] Interactive Requirements: [interactive_requirements] Provide the optimal React 19 architecture: 1. Server vs. Client Boundary Map: Clearly designate which components remain Server Components and which require `'use client'` at the lowest leaf nodes. 2. Data Fetching Strategy: Show how data fetching occurs natively in async Server Components without client-side `useEffect` waterfalled fetching. 3. Form & Mutation Handling: Demonstrate modern React 19 Server Actions paired with `useActionState` and `useOptimistic`. 4. Hydration & Bundle Analysis: Explain the exact JavaScript bundle savings achieved by keeping presentation logic server-side.

Expected AI ResponseVerified Result

### 1. Server vs. Client Boundary Map - `PromptDetailPage (Server Component)`: Root async page. Fetches prompt data and generates static metadata. Zero client JS bundle. - `PromptHeader (Server Component)`: Static title, category badge, and SEO markup. - `PromptVariableCustomizer ('use client')`: Leaf component containing text inputs and dynamic string replacement. - `CopyButton ('use client')`: Leaf client component accessing `navigator.clipboard`. - `BookmarkButton ('use client')`: Leaf client component reading/writing localStorage. - `RelatedPromptsGrid (Server Component)`: Pure server-rendered links and previews.

Tips for Best Results

Techniques to elevate response fidelity

•Specify your exact runtime and dependency versions (e.g. Next.js 15, React 19, TypeScript 5.4) to eliminate outdated syntax hallucinations.
•Ask the model to enumerate potential runtime failure modes, concurrency issues, or null boundary states before generating code.
•Request idiomatic, type-safe solutions with clear unit test skeletons rather than monolithic scripts.

Common Mistakes to Avoid

Frequent failure modes and anti-patterns

•Pasting large unformatted code dumps without indicating the specific function or error you want analyzed.
•Deploying AI-generated code directly to production without verifying memory safety, edge cases, and security vulnerabilities.
•Omitting architectural constraints (such as SSR vs. client component boundaries or database indexing).
