RadiusSchema
@Serializable
Per-corner radius in dp, used by BorderSchema and ShapeSchema.RoundedCornerRectangle.
Maps to RoundedCornerShape(topStart, topEnd, bottomStart, bottomEnd) in Compose. All values are in dp and must be non-negative integers.
DSL helper (mosaic-server):
radius(topStart = 8, topEnd = 8, bottomStart = 8, bottomEnd = 8) // all corners
radius(topStart = 16, topEnd = 16, bottomStart = 0, bottomEnd = 0) // top-onlyContent copied to clipboard
Notes: Corner radii are layout-direction-aware (topStart/topEnd flip in RTL layouts).
