// FIXTURE: fetch-json-schema
// Verifies: fetchJson<T> lowers the T type argument to an injected `schema`
//   property, which the runtime verifies the fetched JSON against. An
//   explicit `schema` parameter wins over injection. fetchJson without a type
//   argument is a compile error; fetchJsonUnchecked is the untyped escape
//   hatch and injects nothing.
