+- [#774]
+  - **Description:**  Updates `KCard` internal structure and style
+  - **Products impact:** This introduces temporary regressions in `KCard` related to removing its control of its height that will instead be controlled by `KCardGrid`. However, `KCard` is required to be always used within `KCardGrid` anyways so ultimately this will be of no real impact. Will be completed by `KCardGrid` soon.
