Architecture patterns for Next.js 16 App Router apps. Use when scaffolding a new app, adding a feature, refactoring code into feature folders, deciding where queries/actions/components live, placing Suspense boundaries, choosing the client/server boundary, designing skeletons, preventing CLS, or enabling Cache Components. Also use when the user asks about RSC composition, `params.then()`, `'use cache'`, `cacheTag`, `updateTag`, or static-shell prerendering.
