+
+**cards**
+- Updated: `variant` - removed default: "asset" - "Gallery cards display one image or video asset. Asset cards show one asset of any type. Collection cards support multiple assets. Horizontal cards place text and one asset side-by-side. Product cards use one thumbnail asset. Flex cards accept any asset type and quantity."
+- Added: `size` (string, default: m) - "Overall size of the card."
+- Added: `state` (string, default: default)
+- Added: `isSelected` (boolean)
+- Added: `isQuiet` (boolean)
+- Added: `isDisabled` (boolean)
+- Added: `hideCheckbox` (boolean) - "If true, the selection checkbox is hidden."
+- Added: `title` (string) - "Optional card title."
+- Added: `description` (string) - "Optional description shown below the title."
+- Added: `actionLabel` (string) - "Optional action button label."
+- Added: `metadata` (string) - "Optional metadata shown below the card."
+- Added: `assetTypes` (array)
+- Added: `imageProportion` (string, default: auto) - "How much of the card container the image or video occupies. Does not apply to document or thumbnail assets."
+- Added: `style` (string, default: primary) - "The style of the card."
+- Added: `imageRatio` (string, default: auto) - "Aspect ratio of the image or video. Does not apply to document or thumbnail assets."
+- Updated: `variant` - "Gallery cards display one image or video asset. Asset cards show one asset of any type. Collection cards support multiple assets. Horizontal cards place text and one asset side-by-side. Product cards use one thumbnail asset. Flex cards accept any asset type and quantity."
+- Added: `required` - ["variant", "assetTypes"]
