// negotiator ships no types, and @types/negotiator can't be a devDependency:
// consumers typecheck our published .ts sources, so the types would have to
// ship as a runtime dependency. Instead we pin the tiny slice of the API we
// use here. This file is intentionally a *script* (no top-level import/export)
// so `declare module` registers as an ambient declaration; it is pulled in via
// the triple-slash reference in `utils.ts`.
