Rework CSS Processing Framework

Rework is a plugin framework for CSS preprocessing in Node.js, built upon the `css` package for AST manipulation. It enables developers to create custom CSS transformations, such as automating vendor prefixing, defining custom properties, or inlining images. At version 1.0.1, it provides a simple API (`rework().use(plugin).toString()`) to apply a chain of plugins to a CSS string. The project saw active development around 2012-2014, with its last npm publish over 10 years ago, indicating it is no longer actively maintained. While it offered a robust plugin ecosystem in its time, its stable version is 1.0.1 and it does not follow a current release cadence. Key differentiators at its peak included a straightforward API for AST access and a rich set of community-contributed plugins, predating and offering an alternative to modern PostCSS.
