responsive:
  mode: event-card-to-compact-reading-order
  reading_order: 'event-card: DOM order remains authoritative at every viewport.'
  rules:
  - Preserve event-card anatomy and primary action in one reading sequence.
  - Wrap text without horizontal page overflow and preserve evidence labels.
accessibility:
  pattern: event-card-navigation
  semantics:
  - Expose event-card as the nearest correct native landmark, article or control.
  keyboard:
  - Tab reaches real actions in DOM order; Enter or Space follows the native control contract.
  focus:
  - Interactive descendants use focus.ring and preserve a visible label.
  motion:
  - Reduced motion removes nonessential transitions without hiding state or evidence.
tokens:
- component.card.background
- component.card.text
- component.card.border
- type.size.metadata
- action.primary
- focus.ring
content:
  required:
