# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## What this repo is

Static one-page website for **Marszalek Architekten** (Perchtoldsdorf, Austria). No build system, no framework — the entire site is a single `index.html` served by nginx inside Docker. A 2-page A4 PDF info sheet lives alongside it as a pre-generated static asset.

## Key commands

### Regenerate the PDF
Requires Node.js and Google Chrome installed locally. Close the PDF in any viewer first (Windows locks open files).
```
node generate-pdf.js
```
The script uses `puppeteer-core` with the system Chrome at `C:\Program Files\Google\Chrome\Application\chrome.exe`. If Chrome moves, update `executablePath` in `generate-pdf.js` and `generate-favicons.js`.

### Regenerate favicons
```
node generate-favicons.js
```
Reads `favicon.svg` and exports `favicon-16x16.png`, `favicon-32x32.png`, and `apple-touch-icon.png` via puppeteer. Run this whenever `favicon.svg` changes.

### Download gallery images from old site
```
node download-gallery-images.js
```
Downloads all extra project gallery images from `old.marszalekarchitekten.at` into `images/`. Safe to re-run — skips files that already exist.

### Build and run via Docker
```
docker compose up --build -d   # build image and start on port 8082
docker compose down            # stop
```

### Install Node deps (only needed to regenerate the PDF or favicons locally)
```
npm install
```

## Architecture

```
index.html                           ← entire website (HTML + CSS + JS)
images/                              ← all portfolio photos, self-hosted (120+ JPEGs)
favicon.svg                          ← master favicon (M monogram, green #99cc00 bg)
favicon-16x16.png                    ← ┐
favicon-32x32.png                    ← ├ generated from favicon.svg via generate-favicons.js
apple-touch-icon.png                 ← ┘
infosheet-template.html              ← HTML source rendered to PDF by Puppeteer
generate-pdf.js                      ← Node script: opens template in Chrome → exports A4 PDF
generate-favicons.js                 ← Node script: renders favicon.svg → PNG at 3 sizes
download-gallery-images.js           ← Node script: fetches gallery images from old WP site
marszalek-architekten-infosheet.pdf  ← pre-generated output; committed to repo
nginx.conf                           ← caching, gzip, PDF download header
Dockerfile                           ← nginx:alpine; copies all static assets
docker-compose.yml                   ← single service, host port 8082 → container port 80
```

### PDF workflow
`infosheet-template.html` is a self-contained 2-page A4 HTML document (mm units, `print-color-adjust: exact`, `page-break-after: always` between pages). `generate-pdf.js` loads it via a `file:///` URL in headless Chrome, waits 1.5 s for Google Fonts, then calls `page.pdf()`. The output PDF is committed — Docker does **not** regenerate it at build time.

### Website structure
`index.html` is a single-page site with five anchor-linked sections:

- **`#home`** — hero with full-viewport background photo
- **`#projekte`** — 3-column portfolio grid; clicking a card opens the lightbox
- **`#leistungen`** — services (2-column grid)
- **`#ueber-uns`** — single team member (Florian Marszalek)
- **`#kontakt`** — contact details + Google Maps iframe + PDF download banner

All images are served from the local `images/` folder — **do not use WordPress CDN URLs**, as the WordPress server blocks hotlinking on mobile.

### Project lightbox
Clicking any `.p-item[data-project]` in the portfolio grid opens a modal (`#lightbox`). All project data (title, description, image list, optional before/after pair) lives in the `projects` object in the inline `<script>`. The lightbox has:
- A main image stage with `‹` / `›` arrow navigation and keyboard arrow-key support
- A scrollable thumbnail strip
- A **before/after comparison slider** (`#ba-section`) shown only for projects that define `beforeAfter: { before, after }` — currently 5 renovation projects: Sanierung, Landhaus, Winzerhaus Neusiedlersee, Dachausbau, Winzerhaus 14. Jhdt.

To add a new project: add a `.p-item` card with `data-project="slug"` in the HTML grid, and add a matching entry to the `projects` JS object.

### Navigation
The nav bar has a **white** (`#ffffff`) background with the logo image (`images/MarszalekLogoGrau.jpg`). The green accent (`#99cc00`) is used only in the PDF header and favicon — not in the nav.

### Third-party integrations
- **Analytics**: Matomo at `analytics.stranto.com`, site ID `3` — snippet in `<head>` of `index.html`.
- **Map**: Google Maps iframe embed (no API key) in `#kontakt`, centred on `48.1176923, 16.2631144` (Elisabethstraße 14, Perchtoldsdorf).
- **Fonts**: Google Fonts (Cormorant Garamond + Inter) — the only remaining external dependency.

### Brand colours
- Green accent: `#99cc00` — PDF header, favicon background
- Near-black: `#0f0f0f` — body text, footer, favicon M lettermark
- Grey-mid: `#999` — secondary labels; CSS var `--grey-mid`

## Deployment (Portainer)
Stack points at `https://git.stranto.com/cgasser/web_marszalekarchitekten`, branch `master`. Site is available on the host at port **8082**.

When content changes: edit `index.html` and/or `infosheet-template.html`, regenerate the PDF with `node generate-pdf.js`, commit all changed files (including any new images), and redeploy the stack in Portainer.
