     * change takes effect on the next request after the operator restarts the stack —
     * nothing is switched mid-session, which is what makes it safe.
     *
     * - Server -> Reverb publishing is pinned to the INTERNAL reverb service (both dev
     *   and prod compose name it `reverb`), so realtime keeps working right after a
     *   domain change and never depends on the new public cert. The browser endpoint is
     *   injected by the layout from DeploymentService::reverbClient().
     * - app.url -> https://<domain> so absolute URL generation matches how the panel is
     *   served. With no domain (bare IP / dev) the env-derived app.url is left as is.
