Migrate a Next.js (App Router) page, template, or MDX/fumadocs content site into this TanStack Start (Vite) project. Use whenever the user wants to port or 迁移 a Next.js page/template into the project, adapt Next.js APIs (next/image, next/link, Metadata, layout.tsx, fumadocs, @next/mdx) to TanStack Start, or stand up MDX content pages with file-based routing. Covers MDX via @mdx-js/rollup + import.meta.glob, root content/ directories, token scoping vs shadcn unification, and the serialization / portal / full-reload / style-to-js / shiki pitfalls that bite every time.
