Claude Code built it with @vercel/blob

Prompt: Add image uploads with a drag-and-drop component and hosted storage.

Grader: The agent wired a drag-and-drop uploader component, a server upload route using handleUpload with type and size limits, and the home page, and the production build passed. It could not verify a real upload because no BLOB_READ_WRITE_TOKEN was available, so it only confirmed the route returns a clear missing-token error.
