Five live products, OhNine, Git Dojo, Statusline Builder, Blueprint, and RAXXO Studio, share one dark UI system
Only two accent colors carry every tool, a cyan and a lime, unchanged since the first product shipped
The one CSS rule that matters most is a shared class prefix that keeps custom code from colliding with the store theme
The payoff is recognition without a logo, and a lot less time spent per launch deciding what a new tool should look like
