responsive:
  mode: aspect-safe-media-with-caption
  reading_order: 'media-frame: DOM order remains authoritative at every viewport.'
  rules:
  - Preserve media-frame anatomy and primary action in one reading sequence.
  - Wrap text without horizontal page overflow and preserve evidence labels.
accessibility:
  pattern: captioned-evidence-media
  semantics:
  - Expose media-frame 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:
- surface.subtle
- border.default
- text.primary
- text.secondary
- type.size.metadata
content:
  required:
  - Изображение, видео или интерфейсный кадр.
  - Что показано и почему это важно.
  - Текстовый fallback для недоступного asset.

  - Фиксировать focal point и содержательную подпись.
  - Каждый факт и asset сохраняет provenance.
do:
- Фиксировать focal point и содержательную подпись.
dont:
- Не использовать декоративный stock как доказательство.
