Vibe Coding & AI IDEs Cheatsheet: .cursorrules, MCP & High-Leverage Prompts

# .cursorrules for Modern TypeScript & Next.js
You are a Senior Full-Stack Software Architect.

## Principles
- Always write clean, idiomatic, fully-typed TypeScript 5+.
- Never use 'any'; create explicit discriminated union types.
- Prefer functional composition and small, testable pure functions.
- For state management, prefer server components and URL searchParams before React state.
- Every async function must include robust error handling and structured logging.

## Verification Routine
- Run 'npm run lint' and 'npm run build' before suggesting that a task is complete.
- Only modify the specific files required for the feature.
