vercel__workflow/.changeset/pre/enable-tanstack-start-vercel-e2e.md

Enable Vercel-prod e2e tests for the tanstack-start workbench now that the Vercel project is connected, and pin its react/@types/react versions to match nextjs-turbopack so pnpm dedupes them across the workspace (the mismatch was breaking the nextjs-turbopack and nextjs-webpack production builds with a MotionStyle type error coming from two @types/react copies).
