+ * In production the Python `hermes dashboard` server injects a one-shot
+ * session token into `index.html` (see `hermes_cli/web_server.py`). The
+ * Vite dev server serves its own `index.html`, so unless we forward that
+ * token, every protected `/api/*` call 401s.
+ *
+ * This plugin fetches the running dashboard's `index.html` on each dev page
+ * load, scrapes the `window.__HERMES_SESSION_TOKEN__` assignment, and
+ * re-injects it into the dev HTML. No-op in production builds.
