-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+This repo is a Next.js app used to generate a static site. The final production image contains only static assets served by Caddy on a read-only filesystem (no Node/npm runtime in the shipped image).
 
-## Getting Started
+## Development (local only)
+- Install deps: `npm install`
+- Run dev server: `npm run dev` then open http://localhost:3000
 
-First, run the development server:
+## Build (production image)
+- `docker build -t www-website .`
+- Runtime is static files only; mount/serve with RO filesystem (e.g., `docker run --read-only --tmpfs /tmp --tmpfs /config --tmpfs /data -p 3000:3000 www-website`).
 
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
-
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
-
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
