- Foldable left panel (user profile) and right panel (task details) - Clicking a task in the list or graph node selects it and shows details - Both views (task list + graph) always mounted via absolute inset-0 for correct canvas dimensions; tabs toggle visibility with opacity - Graph node selection animation: other nodes repel outward (charge -600), then selected node smoothly slides to center (500ms cubic ease-out), then charge restores to -120 and graph stabilizes - Graph re-fits on tab switch and panel resize via ResizeObserver - Fix UUID string IDs throughout (backend returns UUIDs, not integers) - Add TaskDetailPanel, UserPanel components - Add CLAUDE.md project documentation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
