+> contrast steps and hue 220 to 230: surface `#0a1027`, raised `#101929`, border
+> `#212946`, muted `#7e879a`. `foreground` `#f5f4ee` and `accent` `#e8a04f` are

+> `Inter` is replaced by Literata for headings and Libre Franklin for reading.

 ## Purpose
 
 atrib makes agent activity verifiable. Productized atrib is a verifiable action layer for agents: control what runs, coordinate what carries forward, and prove what happened. The design system should make that idea feel concrete: not a vague AI platform, not a crypto dashboard, not an observability clone. The interface should feel like signed evidence entering a chain and becoming usable by the next agent, team, or verifier.
