+# wohlruf-website
+
+Wohlruf marketing landing page — built with [Astro](https://astro.build) + Tailwind CSS.
+
+## Stack
+
+- **Astro** — static site generator, zero-JS by default
+- **Tailwind CSS** — utility-first styling
+- **Output**: pure static HTML/CSS/JS (`dist/`) — FTP-deployable
+
+## Development
+
+```bash
+npm install
+npm run dev       # http://localhost:4321
+```
+
+## Build
+
+```bash
+npm run build     # outputs to dist/
+```
+
+The `dist/` folder contains the complete static site ready for FTP upload.
+
+## Deployment
+
+Copy the contents of `dist/` to your webserver via FTP. No server-side runtime required.
