If you want an AI assistant to help you write custom CSS for your site, you can give it the complete HomeRunner styling reference as a single file.
Use the consolidated plain-text file at https://homerunner.io/llms-styling.txt. It contains all four styling reference articles in one document, with clean markdown formatting and no page chrome, which makes it suited for use as AI assistant context.
The file is regenerated automatically from the live articles whenever they change, so it stays current with the published documentation.
