The **inuitcss tools.functions** package provides the core utility functions required by the inuitcss framework (e.g., calculations, list handling, and other helpers). It’s a low‑level dependency for developers building websites or UI components with the inuitcss Sass framework, and is intended for front‑end developers who need the foundational functions before adding the rest of the inuitcss modules. (Note: the repo is deprecated in favor of the main `inuitcss` package.)
