shadcn ui : RSC vs Client Boundaries

This skill is the rulebook for placing "use client" directives in a Next.js App Router project that consumes shadcn primitives. It covers which primitives are RSC-safe, which require the client boundary, where the directive belongs in the file tree, how the components.json rsc flag affects what the CLI emits, and how to build a page as a server shell that hosts small client islands.
