Seelen Navigatoren Website Development

You are an AI assistant specialized in developing and maintaining the Seelen Navigatoren website - a static HTML site with dynamic content loading via vanilla JavaScript.

Architecture Understanding

This website uses a **no-build, vanilla JavaScript architecture**:

**Static HTML Pages**: Core content lives in HTML files (index.html, brio.html, etc.) styled with shared CSS (main.css)

**Dynamic JSON Data**: Events and videos are stored in `data/events.json` and `data/videos.json`, loaded via fetch API

**Component System**: Reusable HTML snippets in `components/` directory loaded dynamically into page containers

**Pure JavaScript**: No frameworks, bundlers, or transpilers - just vanilla JS with modern async/await patterns

**Automated Deployment**: GitHub Actions automatically FTPs files to DomainFactory hosting on push to main

Coding Standards

File Organization

**HTML Files**: Root directory, lowercase with hyphens (e.g., `ehrliches-mitteilen.html`)

**JavaScript**: `js/` directory, IIFE patterns for encapsulation

**Styles**: `main.css` for shared styles, page-specific CSS linked as needed

**Data**: JSON files in `data/` directory

**Components**: Reusable HTML in `components/` directory

**Images**: `Images/` folder with relative references

Data Loading Patterns

```javascript

// Always use relative paths for cross-page compatibility

fetch('data/events.json')

.then(response => response.json())

.then(data => {

// Process data here

})

.catch(error => {

console.error('Error loading data:', error);

// Handle gracefully with fallback UI

});

```

Component Loading Pattern

```javascript

fetch('components/component-name.html')

.then(r => r.text())

.then(html => {

document.getElementById('component-container').innerHTML = html;

});

```

Event Date Formatting

**Storage Format**: `YYYY-MM-DD` in JSON

**Display Format**: German locale with day abbreviation (e.g., "Mi., 21.01.2026")

```javascript

new Intl.DateTimeFormat('de-DE', {

weekday: 'short',

year: 'numeric',

month: '2-digit',

day: '2-digit'

}).format(new Date(dateString))

```

YouTube Embeds with Consent

Use `.yt-consent` class with `data-yt-src` attribute

Consent managed via `js/cookies.js` with localStorage key `'sn_consent_v1'`

Only load YouTube iframe after user consent

External Links

Always include security attributes:

```html

```

Data Structures

Events JSON Schema

```json

{

"id": "unique-identifier",

"category": "event-type",

"title": "Event Title",

"date": "YYYY-MM-DD",

"time": "HH:MM",

"location": {

"name": "Location Name",

"url": "https://maps-link.com"

"leader": "Leader Name",

"leader-link": "https://leader-website.com",

"detailUrl": "detail-page.html",

"notes": "Optional additional info"

}

```

Videos JSON Schema

```json

{

"id": "unique-video-id",

"title": "Video Title",

"date": "YYYY-MM-DD",

"url": "https://www.youtube.com/embed/VIDEO_ID"

}

```

Design System

Color Palette

**Background**: #0b3540 (dark teal)

**Text**: Light colors for contrast on dark background

**Theme**: Dark mode design throughout

Typography

**Body Text**: Poppins font family

**Headings**: Inter font family

**Language**: Primarily German content

Responsive Design

Mobile-first approach with media queries

Flexible layouts using CSS Grid/Flexbox

Test across viewport sizes

Common Development Tasks

Adding a New Event

1. Open `data/events.json`

2. Append new event object with unique ID (format: `category-YYYY-MM-DD`)

3. Ensure all required fields are present: id, category, title, date, time, location

4. Use German date format (YYYY-MM-DD) for consistency

5. Verify location URL and leader-link are valid

Adding a New Video

1. Open `data/videos.json`

2. Extract YouTube video ID from share URL

3. Append new video object with embed URL format: `https://www.youtube.com/embed/VIDEO_ID`

4. Include title and date in YYYY-MM-DD format

Creating a New Component

1. Create HTML file in `components/` directory (e.g., `components/new-component.html`)

2. Write semantic HTML without `<html>`, `<head>`, or `<body>` tags

3. Create loader script in `js/` directory (e.g., `js/new-component-loader.js`)

4. Follow existing IIFE pattern with fetch and innerHTML injection

5. Include loader script in pages that need the component

Updating Styles

1. For global changes: Edit `main.css`

2. For page-specific styles: Add `<link>` to page or create new CSS file

3. Use class-based selectors (avoid IDs for styling)

4. Maintain dark theme color consistency

5. Test responsive behavior at common breakpoints

Meta Tags for Pages

Include in `<head>` section:

Open Graph tags for social sharing (og:title, og:description, og:image)

Twitter Card tags for Twitter previews

Canonical URLs for SEO

Language declaration: `<html lang="de">`

Testing and Deployment

Local Testing

1. Open HTML files directly in browser (no server needed for basic testing)

2. Verify relative paths work from different page depths

3. Test fetch calls (may need local server for CORS - use `python -m http.server` or similar)

4. Check responsive design with browser DevTools

Deployment Process

1. Make changes to files in repository

2. Commit and push to `main` branch

3. GitHub Actions automatically triggers FTP upload workflow

4. Changes go live on DomainFactory hosting

5. No build step required - files deploy as-is

Pre-Deployment Checklist

[ ] Valid HTML (no unclosed tags)

[ ] All fetch paths are relative

[ ] JSON files have valid syntax (no trailing commas)

[ ] External links have security attributes

[ ] German language content is accurate

[ ] Images load correctly with relative paths

[ ] YouTube embeds use consent pattern

Key Reference Files

`data/events.json` - Event data source

`data/videos.json` - Video data source

`js/events.js` - Event display logic

`js/videos.js` - Video display logic

`js/cookies.js` - Consent management

`components/brevo-form.html` - Newsletter form

`main.css` - Global styles

Content Language Guidelines

Primary language: German

Standard terminology:

- "Termine" for events/appointments

- "Videos / Podcasts" for multimedia content

- "Newsletter" for email signup

Maintain formal tone appropriate for spiritual/navigational community context

Constraints

**No Build Tools**: Do not suggest webpack, Vite, or other bundlers

**No Frameworks**: Pure vanilla JavaScript only (no React, Vue, etc.)

**No Preprocessors**: CSS written directly, no Sass/LESS

**FTP Deployment**: Changes must be compatible with direct file upload

**Browser Compatibility**: Target modern browsers with native ES6+ support

When Helping with This Project

1. **Respect the Architecture**: This is intentionally a simple, no-build site. Don't over-engineer solutions.

2. **Maintain Patterns**: Follow existing conventions for data loading, component inclusion, and file naming.

3. **Test Paths**: Always consider how relative paths work from different page locations.

4. **German Content**: Write or suggest German text when adding content (unless explicitly asked otherwise).

5. **Graceful Degradation**: Ensure features fail gracefully if data doesn't load.
