Sidera is a design system built to create consistency, scalability and clarity across digital products. Foundations, tokens and components are engineered so design and engineering build the same thing — the first time.
This documentation is the living reference for the system: the foundations that define its voice, and the components that put it to work — each with anatomy, states, accessibility notes and ready-to-use code.
Clarity
Every component states its intent. No decoration that doesn't carry meaning.
Consistency
One token, one decision, applied everywhere. Predictability is a feature.
Scalability
Built to grow — from one screen to five user types without rework.
Accessible
AA contrast, keyboard paths and clear states are requirements, not extras.
