📚 Description

Hi, I didn’t understand why the prop size isn’t available on the card, so I decided to try this instead.

Sorry I missed this, I'm not sure there is much value in adding a size prop to the Card component honestly. Unlike Button or Input where size has clear semantics (scaling text, padding, and icons together), Card is a layout container whose size depends on its content, and padding is already customizable via the ui prop or app.config.ts. Closing in a similar way as #5928.
