 * @zync/calendar/server — server-only runtime surface.

 * Token encryption + HMAC verification. These wrap @zync/auth (which depends on
 * Cloudflare Workers runtime globals), so they MUST NOT be reachable from the
 * default `@zync/calendar` barrel — browser code imports only types from there,
 * and pulling this module into a DOM-lib compile drags Workers-typed auth source
 * with it. Import from `@zync/calendar/server` in Worker code only.
