Define Architecture

Define durable, easy-to-change architecture defaults for TypeScript full-stack apps; produce an enforceable architecture brief.

• IS: folder structures, module contracts, middleware pipelines, frontend/backend boundaries; architecture briefs; domain-informed deepening of an existing codebase.
• IS NOT: scaffolding a new repo (scaffold-nextjs for a Next.js turborepo, scaffold-cli for a TypeScript CLI), multi-tenant domain/isolation/routing (multi-tenant-architecture), or structural review of a local diff (pr-reviewer).
