Can I vibecode Unicorn Platform?

Build a comprehensive, self-hosted replacement for Unicorn Platform's core functionalities in an empty repository.
This tool will serve as a local, AI-powered website and landing page builder aimed at startups and solo entrepreneurs.
Use Next.js 15, TypeScript, Tailwind CSS, SQLite, Drizzle ORM, and static export as the technology stack.

The core loop should revolve around:
1. AI-Assisted Page Generation: Implement an AI Co-Pilot (via OpenAI API) that allows users to generate complete layouts, rewrite copy, and suggest components using natural language prompts.
2. Visual Drag-and-Drop Editor: Provide an intuitive, no-code interface enabling users to assemble pages by dragging and dropping pre-designed blocks (Hero, Features, Testimonials, Pricing, FAQ, Footer, Forms).
3. Pre-made Templates: Offer built-in themes tailored for SaaS and tech startups. Enforce a design-token system for typography and colors rather than arbitrary CSS.
4. Built-in Responsive Design: Ensure websites are perfectly responsive. Provide a preview mode to toggle between desktop, tablet, and mobile breakpoints, highlighting layout issues.
5. Core Site Functionalities: Support essential features including basic lead capture forms, fundamental SEO metadata controls, and a simple built-in blogging module.

Ensure the first run works locally with a single, documented command.
All user data, pages, and blog posts must be stored locally in SQLite. Provide an easy portable JSON export/import for backup.
For AI capabilities, read API keys from `.env`, provide `.env.example`. Gracefully handle the absence of API keys by falling back to manual block selection and lorem ipsum.

For the publishing flow:
Generate clean, highly optimized static Next.js output and include documentation on how to deploy this output to a static hosting provider with a custom domain.

Do NOT build multi-tenant accounts, subscription billing, usage telemetry, a plugin marketplace, advanced e-commerce, or memberships. This is a single-user engine.

Include thorough handling of loading, empty, and error states. Add input validation and safe filename handling for local image uploads.
Write focused automated tests for the core page serialization logic and at least one end-to-end happy path for creating and exporting a page. Create a comprehensive README with setup instructions, architecture overview, and backup steps. Conclude by running all tests and detailing the exact terminal commands used.
