CompositeCodec class final

A composite codec (see Codec.composite); const-constructible. Components are individual fields — a const constructor can't build a list — so the signature itself caps the arity at 16. The value is a positional RECORD of the components' decoded values: a record's runtime type comes from its fields' runtime types, so a 2-part composite of string codecs decodes to a value that IS a (String, String) — typed casts and structural equality (repeat-collapse, prefix reuse) work as if it were declared that shape.
