Sass integration for Ember CLI

Ember CLI Sass is an addon for Ember CLI applications that integrates Sass preprocessing into the build pipeline. It provides robust support for generating source maps, configuring include paths, and handling multiple CSS output files via Ember CLI's `outputPaths` configuration. Currently stable at version 11.0.1, the package is actively maintained with recent releases addressing internal chore items and node version compatibility. It defaults to using Dart Sass (compiled to pure JavaScript) for compilation but offers explicit configuration to utilize alternative implementations like `node-sass` (which uses LibSass for potentially faster compilation), allowing developers to choose based on their project's performance and dependency needs. It is a fundamental tool for styling Ember.js projects with Sass, ensuring seamless integration with the Ember CLI build system.
