OpenEnv provides `/reset`, `/step`, `/state`, `/schema`, `/ws`, `/mcp`, `/health`, the Task API under
`/berth_planning/...` and the Gradio UI at `/web`: a "Try Environment" tab where a person plays an episode through the
Task API and a `/ws` session (`/viewer/#/play`), next to OpenEnv's own Playground tab. We add the viewer
(`/viewer/`: Play, and the Explorer of tasks, model rollouts and live episodes) and its read-only JSON under `/api/`.
