Can I vibecode Typedream?

Build a comprehensive, self-hosted open-source alternative to Typedream, operating in an empty repository. This tool will empower users to quickly create modern, responsive websites using an intuitive, Notion-style block-based editor. 

Technology Stack: Next.js 15, React, TypeScript, Tailwind CSS, SQLite (with Drizzle ORM), and static site generation for output. Please stick strictly to this stack without alternatives.

Core Loop & Notion-like Editor: The primary interface should be a drag-and-drop, slash-command driven block editor. Users should be able to type "/" to insert various elements such as headings, paragraphs, buttons, images, cards, and multi-column layouts. The editor must support inline rich text formatting (bold, italic, links). Focus heavily on a clean, minimal aesthetic out of the box, similar to Notion.

AI-Powered Generation: Integrate an AI-assisted workflow using OpenAI's API (or a generic LLM interface). The user should be able to type a prompt (e.g., "Generate a landing page for a SaaS product") and the system will automatically scaffold a complete page layout with wireframes, appropriate block types, and placeholder copy. Include features to use AI to "rewrite" or "expand" specific text blocks within the editor.

Pre-Built Templates & Components: Provide a library of 10+ pre-built, customizable section templates (Hero, Features, Testimonials, Pricing, FAQs, Call to Action, Footer) that users can easily drop into their canvas. Ensure a constrained, modern design-token system is used so that the overall site design remains harmonious without requiring users to mess with arbitrary CSS.

Responsive Design & Preview: The generated sites must be inherently responsive. The editor must feature a preview toggle to immediately see how the site looks on desktop, tablet, and mobile breakpoints. Surface any overflow or layout errors clearly in the UI.

SEO & CMS Capabilities: Include a basic CMS feature allowing users to manage distinct pages (e.g., index, about, blog) and update content efficiently. Every page must have customizable SEO metadata fields (Title, Description, Open Graph image, custom URL slug) to ensure sites are search-engine ready upon deployment.

Local Storage & Static Export: Persist all project data, configurations, and uploaded assets locally using SQLite. Allow straightforward portable JSON exports of the entire site structure. The tool must generate a highly optimized static Next.js output that can be instantly deployed to platforms like Vercel, Netlify, or GitHub Pages. Document the exact deployment steps in the output.

Security & Architecture: Store all secrets (like AI API keys) in a .env file, ship a .env.example, and ensure credentials are never committed. Implement clear empty states, loading skeletons, and graceful error handling when APIs are unavailable. Include safe file handling for image uploads.

Exclusions: Do not implement multi-tenant accounts, billing, advanced analytics, real-time collaboration features, plugin marketplaces, or hosted control planes. Focus strictly on a single-user local application.

Finally, write focused tests for the core AI generation and block transformation logic, and provide a detailed README covering setup, architecture, and deployment instructions.
