Making an entire card clickable simplifies user interactions, especially when there's only one action associated with that card. This design choice reduces the cognitive load, encouraging users to engage more effortlessly with the content. By providing a larger clickable area, you make the UI more accessible and responsive, ultimately streamlining the user journey.

To signal that an entire card is clickable, use a subtle hover effect, such as a color change or shadow, and a pointer cursor. Additionally, you might consider using a faint border.
