The names of the product elements

The name of the type

Hand-written rather than derived, because three details matter and a generic derivation gets all three wrong:

• an absent Noul criteria means the key is absent, never null
• a Choice rubric of null is meaningful and must be emitted as an explicit null value under its key, so dropNullValues is wrong
• key order is deterministic, which is what makes the golden tests stable and identical on the JVM and on Node
