Card is a bordered, elevated container for discrete, self-contained items: things you could reorder, remove, or interact with independently. Cards are NOT the default layout tool. Most content groups don't need a container at all; spacing and alignment create visual grouping naturally. Only reach for a Card when items need clear interaction boundaries or visual comparison in a grid.
