The filled variant puts the title and description, both in the theme's main text color, on a light fill from the theme.
- Check a custom theme in both light and dark mode. A darker fill or a lighter text color can bring the pair under 4.5:1 with nothing warning you.
- If you color the description with classNames, check that pairing too. On a colored or image background, use borderless only when the area behind the text is plain enough to read on.
