Structured client error

Media typeapplication/json

The canonical JSON body of every error response — the single source of truth the frontend binds to. Every AppError serializes as this exact shape, and the generated OpenAPI component ApiErrorBody (with its ErrorCode enum) is what the frontend error schema is generated from, so there is no hand-written error schema on either end.
