 * JSON serializer, backed by Gson.

 *   instead of <-style escapes -- this is an HTTP JSON API, not HTML.
 * - serializeNulls(): matches the previous hand-rolled writer's behavior,
 *   e.g. a proxy result always carries "error": null rather than omitting
 *   the key, which index.html's client-side code expects to see.
