Design Systems That Actually Scale
Most design systems fail for the same reasons. A look at the habits that keep one alive as a product and team grow.

## Why design systems stall
A design system is not a component library. It is an agreement between designers and engineers, and agreements need maintenance.
### Start smaller than feels comfortable
The systems that survive begin with tokens and four or five primitives: button, input, text, stack, and card. Everything else can wait until a real pattern repeats three times.
### Name things after intent, not appearance
`color-danger` outlives `color-red`. `space-md` outlives `space-16`. Intent-based names let you rethemed the whole product without touching a single component.
### Make the easy path the correct path
If using the system is slower than writing custom CSS, people will write custom CSS. Invest in documentation, copyable examples, and sensible defaults.
### Version and communicate changes
Breaking changes are fine. Surprising breaking changes are not. Treat your system like the internal product it is, complete with a changelog.
A good system feels less like a rulebook and more like a set of sharp tools that happen to match.
