Background
The Codex-style WebUI polish needs repeatable visual QA for the ready three-pane workbench. Today, running the Vite dev server without a backend drops into the first-world onboarding flow, so the main WorldSidebar / MainPanel / InspectorPanel state cannot be reviewed in a browser without external data.
Proposal
Add a dev-only seeded/demo mode or fixture endpoint that can render a representative narrative workspace with:
- at least one world, session, and active agent
- sample user/assistant/tool/approval/system timeline cells
- story/files/agents/run inspector data
- running/idle/approval states for visual regression checks
Acceptance Criteria
- A developer can run the WebUI locally and open a stable URL or enable a documented flag to see the ready three-pane workbench.
- The demo state does not affect production API behavior.
- The fixture supports desktop and mobile visual QA.
