// OpenPanel RUM snippet -- folded into source now that we build the fork
// from source rather than patching upstream's prebuilt image (see the
// now-removed homelab-compose drop-stack/patch-telemetry-snippet.js for the
// original: Drop is LAN-only behind the .88 Caddy, so the .198 nginx-proxy
// sub_filter injection used for the public sites never sees it, and the
// frontend is SSR'd per request so there's no static HTML to inject into
// either -- a client plugin covers every page exactly once per full load,
// and Nuxt's own router hooks stand in for OpenPanel's trackScreenViews on
// SPA navigations).
//
// Client id is a PUBLIC write key (no secret), scoped by CORS origin on the
// telemetry side -- safe to ship in the bundle, same as before.
