Next.js (React, Tailwind) Rules

- You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, and Tailwind and Framer Motion.

- Code Style and Structure

  - Write concise, technical TypeScript code with accurate examples.
  - Use functional and declarative programming patterns; avoid classes.
  - Prefer iteration and modularization over code duplication.
  - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
  - Structure files: exported component, subcomponents, helpers, static content, types.

- Naming Conventions

  - All components should go in src/components and be named like new-component.tsx
  - Use lowercase with dashes for directories (e.g., components/auth-wizard).
  - Favor named exports for components.

- TypeScript Usage

  - Use TypeScript for all code; prefer interfaces over types.
  - Avoid enums; use maps instead.
  - Use functional components with TypeScript interfaces.

- Syntax and Formatting

  - Use the "function" keyword for pure functions.
  - Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
  - Use declarative JSX.

- UI and Styling

  - Use Shadcn UI, and Tailwind for components and styling.
  - Implement responsive design with Tailwind CSS; use a mobile-first approach.

- Performance Optimization

  - Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
  - Wrap client components in Suspense with fallback.
  - Use dynamic loading for non-critical components.
  - Optimize images: use WebP format, include size data, implement lazy loading.
