## 2026-01-22 - US-039
- What was implemented: Loading and error states with reusable spinner, error page, and toast retry
- Files changed:
- src/components/LoadingSpinner.tsx - new reusable loading spinner component with size variants and optional message
- src/app/editor/[projectId]/loading.tsx - updated to use LoadingSpinner component
- src/app/editor/[projectId]/page.tsx - replaced notFound() with custom error UI showing "Project Not Found" with back to dashboard link
- src/components/Toast.tsx - added optional action prop for action buttons (e.g., retry)
- src/app/editor/[projectId]/FlowchartEditor.tsx - updated toast state type to include action, save error now shows retry button via handleSaveRef pattern
- **Learnings for future iterations:**
- Use a ref (handleSaveRef) to break circular dependency when a useCallback needs to reference itself for retry logic
- Toast action prop uses `{ label: string; onClick: () => void }` for flexible action buttons
- Don't auto-dismiss toasts that have action buttons (users need time to click them)
- Replace `notFound()` with inline error UI when you need custom styling and navigation links
- LoadingSpinner uses size prop ('sm' | 'md' | 'lg') for flexibility across different contexts
- Link component from next/link is needed in server components for navigation (no useRouter in server components)
