+Add Parcel transformer for importing CSS files as Lit tagged template literals
+
+This new package provides a Parcel transformer that converts CSS imports into Lit's `css` tagged template literals, enabling seamless CSS-in-JS workflow for Lit components in Parcel projects.
+
+Features:
+- Transforms CSS files into Lit `css` tagged templates during Parcel builds
+- Supports configuration via package.json
+- Compatible with CSS preprocessors through custom transform functions
+- Leverages the core `@pwrs/lit-css` transform library
+- Works with Parcel 2.x
