Try the rules free. Buy the full set when it earns it.
DESIGN-lite.md is the free edition of Convergence. It's not a locked teaser — it's a real, working subset: the core color/type/spacing tokens, the Ten Principles, and the highest-leverage conversion rules. Drop it into Claude, Cursor, ChatGPT or v0, ship a screen, and see the difference yourself. When it earns the upgrade, the full system is $5.
