113 generic struct with primitives

// RED PIN (type-system design walk, 2026-07-06/07). REWRITTEN from the
// dead `Box<EmailAddress>` generation. A stamped name whose parameter
// is a KORU-MINTED nominal type (not a host primitive): `~string`
// declares the nominal EmailAddress; the stamp references it by its
// registry name. This is the pin that requires field types to
// REFERENCE REGISTRY ENTRIES rather than bottom out in host strings —
// `box#EmailAddress` cannot be resolved by passing text to Zig.
// Spelling PROVISIONAL.
