Can I vibecode SimpleMind?

Act as an expert frontend developer and build a usable personal replacement for the core loop of SimpleMind, a popular mind-mapping application.

**Tech Stack**: Use React, TypeScript, Vite, and IndexedDB for local storage. For the canvas, you may use React Flow or build a custom SVG/HTML5 Canvas renderer. Use Tailwind CSS or vanilla CSS for styling.

**Core Job**: Build a browser-based mind mapping editor that allows users to visually brainstorm, organize thoughts, and structure information.

**Key Features to Implement**:
1. **Interactive Canvas**: Implement an infinite canvas with smooth panning and zooming.
2. **Node Management**: Users can create, edit, delete, and connect topics (nodes). Support drag-and-drop to freely reorganize the mind map's structure.
3. **Layouts**: Implement a "free-form" layout (custom node placement) and an auto-layout mode (e.g., horizontal tree or radial) to automatically organize the map.
4. **Branch Controls**: Add the ability to collapse and expand branches to focus on specific sections.
5. **Styling**: Allow users to customize the visual styling of nodes and connections (colors, borders, line types). Provide built-in themes.
6. **Rich Content**: Support rich text, checkboxes, and icons within nodes.
7. **Cross-linking**: Allow users to draw arbitrary connections (cross-links) between any two nodes to illustrate complex relationships.
8. **Keyboard Shortcuts**: Implement robust keyboard navigation ('Tab' for child node, 'Enter' for sibling, arrows for navigation, 'Delete' to remove).
9. **Outline View**: Provide a sidebar displaying a structured, text-based outline of the entire mind map hierarchy that updates in real-time.
10. **Data Persistence**: Autosave all data locally using IndexedDB.
11. **Import/Export**: Export the mind map as an image (PNG/SVG) and as a structured text outline (Markdown/JSON). Support importing JSON.

**Constraints & Best Practices**:
- Start from an empty folder and create the complete working project.
- Make the default mode single-user and private. All data must remain strictly local.
- Do not add analytics, telemetry, ads, or third-party accounts.
- Build a polished, responsive interface with clear empty, loading, and error states.
- Ensure accessible keyboard navigation and sensible color contrast.
- Validate all untrusted input.
- Exclude paid-product features like multiplayer collaboration, cloud sync, and presentation modes.
- Write focused unit tests for the data model.
- Create a clear README with setup instructions and architecture details.
- Provide scripts for install, development, and build. Run tests before finishing to ensure a flawless out-of-the-box experience.
