Required
Uses a small brand UiBadge beside the label and the native required attribute when the control supports it.
Foundations, components, and patterns now live in separate pages so demos stay readable and reusable.
UI Components
Each card documents one source of truth, its variants, validation states, and a functional preview. Application pages must compose these components instead of recreating styles locally.
Form states are owned by the UI components. Product pages should pass state props such as required, invalid, helpText, and errorMessage instead of recreating field labels, badges, borders, or messages locally.
Design System/components/form-states.md Uses a small brand UiBadge beside the label and the native required attribute when the control supports it.
Uses border-control-error, text-error, and aria-invalid.
Uses type-caption-medium and text-muted. It is linked to the control through aria-describedby.
Disables interaction, lowers opacity, and keeps the component responsible for the disabled visual state.
