 * This plugin detects side-effect imports of CSS files and adds a suffix
 * to the import path, e.g. `import "./styles.css"` is transformed to
 * `import "./styles.css?__remix_sideEffect__"`). This allows them to be
 * differentiated from non-side-effect imports so that they can be added
 * to the CSS bundle. This is primarily designed to support packages that
 * import plain CSS files directly within JS files.
