App Router shell
Start with a typed page structure, metadata, and production-safe layout defaults.

A Next.js base with App Router, Tailwind, shadcn/ui, server-action boundaries, logging conventions, and sandbox deployment hooks already in place.
Start with a typed page structure, metadata, and production-safe layout defaults.

Keep business logic behind server-side actions and optional Noop integrations.
Build, containerize, deploy, and observe through the template runtime contract.
