Can I vibecode Canva?

Build an exceptional, browser-based canvas design editor designed to serve as a modern, local replacement for Canva Pro. This tool must be vibe-coded to perfection using a modern stack: React (Next.js or Vite), TypeScript, Tailwind CSS, and Fabric.js for the core canvas engine. The interface should rival the best modern web apps, featuring a buttery smooth UI, beautiful glassmorphic overlays, vibrant yet tasteful color palettes, and satisfying micro-animations on user interactions.

Key Requirements:
1. **Editing Engine:** Build the editor around Fabric.js. Implement robust editing capabilities: adding text with local custom fonts, uploading images via drag-and-drop, drawing basic shapes (rectangles, lines, circles), and managing layers (reorder, lock, hide). Implement snap-to guides, center alignment helpers, and grouping.
2. **Presets & Canvas Setup:** Offer predefined canvas sizes for common formats (Instagram post 1080x1080, IG story 1080x1920, X header 1500x500, A4 poster) as well as a beautiful custom-size dialog.
3. **Brand Kit & Assets:** Implement a local 'Brand Panel'. It should load a `brand.json` configuration specifying the user's primary colors, secondary colors, and typography. Render these as one-click swatches in the editor. Allow the user to easily access a local folder of their own images to act as their personal asset library.
4. **Serialization & Export:** Every design must be serializable to a local JSON file (e.g., `designs/<name>.json`) and reopen perfectly intact. Implement a "duplicate-as-template" feature. For final output, support high-res PNG export (1x and 2x) directly from the canvas, and PDF export by passing the high-res image into a local PDF generation library or utilizing a headless browser print method.
5. **Local-First & Privacy:** The application must be entirely local. No accounts, no cloud sync, no telemetry, no tracking. Include a tiny local Express server or use a Tauri backend if necessary to handle saving files directly to the user's disk.
6. **Visual Excellence:** The application must look stunning. Use a highly curated dark theme or a pristine light theme with ample whitespace. Ensure all toolbars and properties panels are intuitive, cleanly laid out, and responsive.
7. **Documentation:** Provide a clear README explaining how to add new local fonts, where designs are saved on disk, and how to run the application locally. Ship with at least 3 beautiful starter designs built entirely from the provided tools.
