Can I vibe code Sanity?

Build a lightweight, self-hosted Headless CMS backend and admin dashboard using Next.js 14, Tailwind CSS, PostgreSQL, and Prisma ORM.

1. DATA MODEL:
- Document: id, slug, schemaType (e.g. 'productPage', 'article'), draftData (JSONB), publishedData (JSONB), status ('draft', 'published'), createdAt, updatedAt.
- Asset: id, url, filename, mimeType, size, focalPoint (JSONB: {x, y}).
- User: id, email, role ('admin', 'editor').

2. ADMIN DASHBOARD UI:
- Dynamic Form Generator: Parse schema JSON definitions to render inputs (Text, RichText via TipTap, Asset Picker, Document References).
- Visual State Manager: Dual view for 'Draft' vs 'Published' with a 'Publish' button that copies draftData to publishedData.
- Media Library: Grid view for image uploads, drag-and-drop file uploader (saved to S3 bucket), and focal-point picker UI.

3. API LAYER:
- REST API `/api/content/[schemaType]/[slug]`: Returns publishedData by default, or draftData if query string `preview=true` and valid API secret header is present.
- Dynamic Query Filtering: Allow filtering by nested JSON attributes via query params (e.g. `?filter[category]=shoes`).
- Webhooks: Fire POST requests to configured URLs whenever a document status changes to 'published'.

4. FAILURE MODES & REQUIREMENTS:
- Enforce schema validation on draft save using Zod.
- Return clear HTTP 400 errors if required fields are missing upon publishing.
- Lock document edits if another user is actively modifying (simple pessimistic optimistic lock timestamp).

5. OUT OF SCOPE:
- Real-time CRDT multi-user collaborative editing.
- Custom GROQ query parsing (use standard REST/JSON responses).
- Dynamic image transformation proxy (rely on S3 directly).
