Simplicity
The simplest interface that preserves user value wins.
The few rules that decide every interface.
This system exists so we improve the UI once — in the shared theme and components — and every product inherits it, pixel-perfect. That turns UI quality from per-product rebuilding into a single lever: improve a component once, and the whole fleet gets better at once. It is how UI improvement compounds.
The simplest interface that preserves user value wins.
Every element must help the user understand, decide, act, recover, or trust.
Every product uses the shared theme, components, icons, and state recipes.
The best path is the one users understand without instruction.
Polish earns attention only when clarity, speed, and usefulness are already true.
