ariaLabelstring—Accessible label applied to the card content area. Defaults to the title and subtitle joined with an em dash.
Accessibility
- The card content area is focusable with tabIndex={0}.
- Arrow keys move the dot effect in steps based on 20% of the content area's smaller dimension; the handler prevents the default arrow-key action.
- Focusing the content area activates the effect at its center; blurring it resets the effect.
- Set ariaLabel to provide a suitable accessible label for the content area, especially when the visible title and subtitle do not describe it adequately.
- CTA controls are links rendered through the Button component. Give each CTA meaningful text and a working URL; the default "#" URL intentionally prevents navigation.
