/**
 * Google wraps every outbound result in `https://www.google.com/goto?url=<opaque
 * token>`. The token is a protobuf blob with no URL in it and the target appears
 * nowhere in the page, so the only way to learn it is to follow the link.
 *
 * It is followed in Chrome, lazily, one link at a time, when the caller asks
 * (see `resolveLink` in search.ts) — not here, and not for every result. A
 * plain HTTP client gets Google's "Verifying your request" countdown after a
 * handful of requests; the browser, with its own profile, gets the redirect.
