Studio diagnostics viewer

A client-only viewer for JSON copied from the Sanity Studio diagnostics panel. Pasted diagnostics stay in the browser and are not uploaded.

bash

pnpm dev:studio-diagnostics
pnpm build:studio-diagnostics

The included vercel.json builds the workspace package and serves the Vite SPA with history fallback. It does not create the Vercel project.

For the one-time setup, create a project under the sanity-sandbox Vercel team, connect it to this repository, and use dev/studio-diagnostics-viewer as its Root Directory. Once connected, the Vercel Git integration creates PR previews and deploys main to production.
