docs/INTEGRATION.md is the API reference for building the front end against the
sidecar: base URL, auth (Bearer / X-Api-Key / ?token=), protocol versioning, the
rich /health, the WebSocket live feed with a full event catalog, every REST query
and command (char/roster/vendors/link/towncrier/history/economy), the status-code
table, a worked character-page example, and current caveats. Payloads are the real
shapes captured during testing. Linked from the top-level README.
