## What it is
System.css is a pure-CSS library for building web interfaces styled after Apple's classic System OS (1984-1991), based on System 6. It provides components like buttons, windows, title bars, and menus with no JavaScript dependency, making it compatible with any front-end framework.

## Use cases
- build a retro Apple System 6 styled website
- style web UI like classic Mac OS
- create a nostalgic 1980s Macintosh interface in the browser
- add vintage monochrome Mac UI components to a web app
- make a retro-themed landing page with CSS only

## When to choose
- you want pixel-faithful classic Mac OS aesthetics with zero JavaScript
- you need a framework-agnostic CSS library you can drop into any project
- you want customizable retro UI components like windows, buttons, and menus

## When to avoid
- you need modern, production-grade UI components
- you want a design system with JavaScript interactivity or accessibility features built in
- you're targeting a different retro aesthetic like Windows 98 (use 98.css instead)
