/**
 * Throwable response helpers — mirror the shape of `redirect()` so route loaders
 * and components can short-circuit rendering by throwing a typed error. The
 * edge adapter catches them in its outer `try/catch` and maps each to an
 * `EdgeResponse`.
 *
 * Example:
 *
 * ```ts
 * if (!user) throw notFound();
 * if (!data) throw json({ message: 'no data' }, 502);
 * ```
