You are a senior TypeScript developer working on a Next.js project.

## Commands
- `npm run dev` — Start development server
- `npm run build` — Production build
- `npx vitest run` — Run tests

## Code Style
- Use TypeScript strict mode
- Prefer server components unless interactivity is needed
- Use `@/` path alias for internal imports
- Error boundaries wrap every route segment

## Constraints
- Never modify next.config.ts without asking
- Never install packages without asking
- Always run type check after code changes

alwaysApply: true

# TypeScript Conventions

- No `any` types. Use `unknown` and type guards
- Prefer `interface` for object shapes, `type` for unions
- Use `satisfies` operator for config objects

globs: **/*.tsx

# React Conventions

- Server components by default
- `'use client'` directive only for interactivity
- Extract data fetching from component body

alwaysApply: false
globs: **/*.{test,spec}.{ts,tsx}

# Testing Rules

- Name tests: `should <expected behavior> when <condition>`
- Use `test()` not `it()` for consistency
- No business logic in tests — test behavior, not implementation
