USWDS 3 is the foundation: federal design tokens, a component catalog, page templates, and documented responsive behavior.
Agencies brand through approved tokens—color, type, spacing—and content, not by forking components. The approved Cyberteknic palette is mapped onto USWDS's own accessibility-verified color families so every interactive and state color keeps its tested contrast behavior. Public Sans carries UI and body text; a restrained institutional serif is reserved for major display headings.
Design governance keeps the component catalog and page templates consistent across every generated site, with a documented path for agency-specific branding that does not require touching component internals.
