The whole fix's correctness rests on isNodeRuntime being false in the browser (so the
interactive live-DOM comment branch still runs), and that is NOT covered by any test
(client vitest runs under jsdom->node where isNodeRuntime is true). Document it: Vite
substitutes only process.env, not the bare process object, so typeof process is
undefined in the client bundle; do not add a process polyfill without revisiting this
guard, or comment interactivity dies silently.
