+## Feature
+POS Phase 1 ticket 006: `apps/pos` Next.js application skeleton.
+
+## Objetivo
+Create the `apps/pos` Next.js app with: package.json, next.config.ts, tsconfig.json, Tailwind, root layout, auth login page, API proxy route, middleware, POS API client, permissions, money utils, idempotency utils, terminal page shell.
+
+## Diseño
+- Next.js 15 App Router; route groups (auth) and (terminal)
+- Middleware enforces session cookie; redirects to /login if absent
+- API proxy: `/api/[...path]` proxies to backend preserving cookies + terminal header
+- No server-side DB; all data via API
