Adapt by capability, not device label

Components declare supported inputs, presentations, attention contexts, accessibility preferences, environments, and fallbacks.

実践ガイダンス

Preserve intent while adapting hierarchy and interaction; never assume hover, precision, motion, transparency, or a fixed viewport.

推奨

  • Publish a capability declaration and fallback
  • Test compact, regular, assistive, localized, and degraded states

非推奨

  • Treat mobile, desktop, and spatial as scaled skins

検証契約
