# Coss UI Setup Follow this skill strictly. ## Prerequisite Verify that the current project is a shadcn TanStack Start monorepo with a shared UI package. If it is not, stop and ask the user to run `$project-setup` first.

Remove only the generated Next.js font wiring that the CSS setup replaces. Verify that TanStack's `src
