-● Huddle: The top-level type representing a collection of rules.
-● HuddleItem: Represents individual items within a Huddle, such as rules, groups, or generic rules.
-● Rule: A named type definition.
-● Named: A type wrapper for associating a name, value, and optional description with an item.
-● Value: A type representing primitive CBOR values.
-● Group: Represents a collection of entries within a map or array.

-● +>: Upper bound
-● opt: Optional (0 or 1 occurrences)
