 * The readonly projection: `readonly List<T>` and its mutable twin.
 *
 * Three functions, one rule — a readonly view is a flag on the container kinds
 * that have one, and projecting through `optional` and `union` rebuilds the
 * wrapper rather than dropping it, so `readonly List<T>?` stays optional.
