Cross-Environment querySelectorAll Implementation

This package provides a JavaScript implementation of `querySelectorAll`, designed to offer consistent DOM querying functionality across various environments, including Node.js (with `jsdom`) and older browser contexts. The current stable version is 2.0.0, released in August 2019. The project exhibits a slow release cadence, with no substantial updates since its last major version. Its key differentiator is providing a polyfill-like solution for `querySelectorAll` where native implementations might be absent or incomplete, ensuring broader compatibility for selector-based DOM manipulation. It serves as a foundational utility for projects requiring reliable CSS selector-based element retrieval outside of modern browser engines.
