/**
 * InteractiveEditor — tabbed editor for one interactive experience.
 *
 * UI-2a placeholder — just renders the project header and a tab
 * strip with the six future sub-panels disabled. The real panel
 * bodies land in UI-3 / UI-4 / UI-5:
 *
 *   UI-3: Graph   — DAG visualizer over ix_nodes + ix_edges
 *         Catalog — action_catalog CRUD with level/scheme gates
 *   UI-4: Rules   — personalization-rule DSL builder
 *         QA      — run checks, render issues
 *         Publish — channel picker + publish flow
 *   UI-5: Analytics — experience + session rollups
 *
 * The editor owns the currently-selected tab in local state;
 * switching tabs never unmounts the project header so the
 * breadcrumb + status badge stay stable.
