summary
Ten concrete rules claim to make large‑scale CSS manageable: keep files small and modular, centralize config into use variables and placeholders (Sass examples), and name components with BEM single-class selectors to keep specificity low.

A live MMO CSS game is built and runs as a demo, proving the practices in action.
