Cautions
- Test COLRv1 in the browsers you support, especially if it changes layout, text handling, or interaction behavior.
- Plan a fallback or acceptable degradation path when support is still limited.
Accessibility
- Check readability with zoom, narrow screens, and mixed-language content so text remains understandable.
