Browser-native behavior

Progressive enhancement
Enhance the experience where support exists while keeping a solid baseline elsewhere.
Cautions
- Check browser support and actual product need before adding a new platform feature widely.
- Keep feature usage understandable so future contributors know why it was chosen.
Accessibility
- New platform features should still preserve readable defaults and robust interaction patterns.
- Verify that enhancement paths do not leave unsupported environments with a broken experience.
