Set up a new project for me from scratch.

What I’m building: [describe the project] Stack: [e.g. Next.js + TypeScript + Tailwind + Prisma + PostgreSQL] Infra: [e.g. Docker, runs on a VPS, deployed via GitHub Actions]

Give me:

  1. The folder structure with a one-line explanation for each directory
  2. The config files I need (package.json, tsconfig, docker-compose, .env.example, etc.) — complete and ready to use
  3. A minimal “hello world” that proves the stack is wired up correctly
  4. The commands to go from zero to running locally

No boilerplate comments in the code. No TODO placeholders. Everything you give me should work when I paste it.
