`useClient()` rebuilds its verbs on every render, so `get` has a new identity each time. It was in the
effect's dependency list, so the effect re-ran on every render — and its first act is setReady(false),
which renders again, which builds another `get`, which re-runs the effect. The frame never mounted.
Through a ref instead, with the effect depending only on the port.
This trap is documented in CLAUDE.md and it is the same one that silently disabled every playback
report in the Jellyfin player. The platform's own Preview panel sidesteps it by depending on neither
the client nor the URL, which is what this now does.
