cssnano Utilities

cssnano-utils is a foundational library providing essential utility methods and a PostCSS plugin specifically designed for use within the cssnano ecosystem. It offers functionalities like `rawCache` for managing raw value formatting of AST nodes, `getArguments` for parsing CSS function arguments, and `sameParent` for checking node relationships within the PostCSS AST. Currently at version 5.0.1, this package does not have an independent release cadence but updates in tandem with its parent project, cssnano, which sees frequent bug fix and minor releases (e.g., v7.1.5, v7.1.4, v7.1.3 within a short timeframe). Its key differentiator is its specialized nature, providing low-level, performance-optimized utilities that are integral to how cssnano plugins analyze and transform CSS, rather than being a standalone CSS processing tool.
