Design System Token Settings

Token settings pages must show semantics, aliases, modes, affected components, version diffs, and release risk together, not only color and number inputs.

Design tokens are design decisions that move across design tools, code platforms, and component libraries. A settings page does not only edit values; it explains how a value is referenced, how it changes by mode, and which components and versions it affects.96%

Public-Service Trust Rails and Recovery

Public-service interfaces must make official identity, responsible organization, legal links, task title, form semantics, error summaries, and recovery paths into verifiable page structure instead of merely applying blue-white civic styling.

Trust in public services comes from an inspectable responsibility chain and recoverable task flow: users need to know whether the service is official, who is responsible, whether the connection is safe, why information is needed, how to fix mistakes, and where privacy/accessibility/oversight information lives.95%

Component Governance Review Flow

Component Governance Review Flow turns a frequent interface judgment into an executable constraint before generation.

A design system needs to record why components are added, how they are reused, and when they are deprecated, not just list components.86%

Design Token Governance

Tokens should express roles and constraints, not merely store colors, type, and spacing.

Maintainable tokens need names, scope, defaults, and prohibited uses so humans and agents can share them.82%
