StandardSchemaV1

The Standard Schema v1 interface, inlined.

Inlined rather than depended on, which is the whole point of the spec: it is a shape, not a package. Zod, Valibot and ArkType all expose ~standard, so accepting this type means accepting any of them — and any hand-written validator — without this library taking a dependency on, or a position about, which one you use.

Only the parts that are read here are declared. The full spec has more.
