     *
     * `User-Agent`, `X-Forwarded-For`, `X-HawkSearch-ClientGuid`, and
     * `X-HawkSearch-IgnoreTracking` are values a server-side HawkSearch SDK
     * would normally populate automatically. Because this library calls the API
     * directly from the browser, it reconstructs them here by hand.
     *
     * Everything is best-effort and defensive on purpose:
     * - `User-Agent` is a browser "forbidden header" — `fetch` may silently drop
     *   it or throw when it's set.
     * - The library also runs in sandboxed iframes (e.g. BigCommerce), SSR /
     *   hydration, and jsdom tests, where `window` / `navigator` / the
     *   `HawkSearch` global may be undefined, or where `new Headers()` /
     *   `headers.set()` themselves can throw.
     *
     * These headers are optional enrichment (analytics / geo / tracking), never
     * required for the request to succeed — so a failure to build any one of
     * them must never break a search. Each header is resolved and set in its own
     * try/catch (see {@link setHeaderSafe}): a failing header is logged in debug
     * mode and skipped while the rest still go out.
