  • Users can lead with measured outcome and credible customer context while understanding the current state, available choices, and resulting consequence.

This proof heroes pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
  • Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
  • Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.
