# Next.js 14 Fullstack Rule Engine

Standardized workflow rules for building performant web applications.

## Architecture Standards
1. App Router default: Server Components by default; add 'use client' only when browser APIs or hooks are required.
2. Data fetching: Fetch directly in Server Components; use Server Actions for mutations.
3. Styling: Tailwind utility classes with zero negative letter-spacing and semantic color tokens.
