Card

Brutalist Card is a direct styled-only grouping surface with no Base counterpart.

• The public surface is deliberately limited to Root, Header, Content, and Footer.
• Root is a passive square paper panel with a 2px ink frame and hard offset shadow; it has no role, focus, activation, or selection mode.
• Header and Footer own directional ink separators and layout; Content owns horizontal spacing.
• Title and description are ordinary content. Actions compose Button or Link children, which retain their own semantics.

Use Card for passive visual grouping. Selection, disclosure, navigation, and activation belong to their corresponding protocols rather than Card modes.
