**Tech Stack:**
- Astro 4.x (Static Site Generator)
- TypeScript (strict mode)
- Vanilla CSS with CSS Custom Properties
- Docker + Nginx for deployment
- Node.js 18+

## Color Palette

The site uses CSS custom properties for theming. All colors are defined in `src/layouts/BaseLayout.astro`:

```css
--color-bg: #1e1e2e           /* Dark background (Catppuccin Mocha base) */
--color-text: #cdd6f4          /* Light text */
--color-text-dim: #a6adc8      /* Dimmed text for less emphasis */
--color-accent: #cba6f7        /* Mauve accent */
--color-accent-bright: #f5c2e7 /* Pink accent for highlights */
--color-surface: #313244       /* Surface color for borders/cards */
--color-blue: #89b4fa          /* Blue for links */
--color-green: #a6e3a1         /* Green for code */
--color-peach: #fab387         /* Peach for labels */
```

## Component Architecture

### BaseLayout.astro

The base layout provides:
- HTML structure and meta tags
- Global CSS reset and typography
- CSS custom properties for theming
- Global animations (fadeIn)

### index.astro

The main page includes these sections:
1. **Header** - Title
2. **About** - Introduction, age, status
3. **Cryptographic Keys** - PGP fingerprint and SSH public key
4. **Games** - Games Latte plays
5. **Socials** - Links to social platforms
6. **Services** - Self-hosted services
7. **Support** - Crypto donation addresses
8. **Blog** - Link to `/blog`
9. **Footer** - Credits

### blog/index.astro

Blog listing page at `/blog`. Fetches all non-draft posts from the `blog` content collection, sorted by date descending.

### blog/[...slug].astro

Individual blog post page. Renders Markdown content using Astro's `<Content />` component. Styles for prose content (headings, paragraphs, code blocks, images, etc.) are scoped within `.content :global(...)`.

### src/content/config.ts

Defines the `blog` content collection schema:
- `title` (string) — post title
- `date` (date) — publish date, used for sorting
- `description` (string) — shown on the listing page
- `draft` (boolean, optional) — set to `true` to hide from listing

### 404.astro

Custom error page with:
- Themed styling matching the cozy aesthetic
- Clear error message ("Lost in the Den?")
- Action buttons to return home or visit Gitea
- Responsive design for all devices

## Development Workflow

### Local Development

1. Install dependencies:
```bash
npm install
```

2. Start dev server (with hot reload):
```bash
npm run dev
```
Server runs at `http://localhost:4321`

3. Build for production:
```bash
npm run build
```
Output goes to `dist/` directory

4. Preview production build:
```bash
npm run preview
```

### Making Changes

**Adding a new section:**
1. Edit `src/pages/index.astro`
2. Add a new `<section class="section new-section">` block
3. Style it in the `<style>` tag at the bottom
4. Use the `.card` class for consistent styling

**Changing colors:**
1. Edit CSS custom properties in `src/layouts/BaseLayout.astro`
2. All components will automatically update

**Adding a service:**
1. Add a new `.service-item` div in the Services section
2. Follow the existing structure with h3 link and description

**Adding images:**
1. Place images in `public/blog/<post-slug>/` directory
2. Reference in Markdown with `/blog/<post-slug>/image.jpg`
3. They'll be served as static assets by nginx

**Adding a blog post:**
1. Create `src/content/blog/my-post-slug.md`
2. Add frontmatter: `title`, `date`, `description` (and optionally `draft: true`)
3. Write content in Markdown below the frontmatter
4. The post appears automatically at `/blog/my-post-slug`

## Docker Deployment

### Building the Image

The Dockerfile uses a multi-stage build:
- Stage 1: Node builder (builds Astro site)
- Stage 2: Nginx server (serves static files)

```bash
docker build -t cozy-den .
```

### Running Locally

```bash
docker run -d -p 3000:80 --name cozy-den cozy-den
```

Access at `http://localhost:3000`

### Using Docker Compose

```bash
# Start
docker-compose up -d

# Stop
docker-compose down

# View logs
docker-compose logs -f
```

### Deploying to Gitea Registry

```bash
# Tag for Gitea registry
docker tag cozy-den git.hiddenden.cafe/mats/cozy-den:latest

# Login to Gitea
docker login git.hiddenden.cafe

# Push
docker push git.hiddenden.cafe/mats/cozy-den:latest
```

## Astro-Specific Information

### File Extensions
- `.astro` - Astro components (HTML-like syntax with embedded JS)
- `.mjs` - ES module JavaScript files

### Frontmatter
Code between `---` at the top of .astro files runs at build time:
```astro
---
// This runs at build time (server-side)
const title = "My Page";
---
<h1>{title}</h1>
```

### Styling
- `<style>` tags in .astro files are scoped by default
- Use `<style is:global>` for global styles
- CSS is processed and optimized automatically

### Static Generation
Astro generates static HTML at build time. No JavaScript runtime needed for this site (pure HTML/CSS output).

## Common Tasks

### Task: Add a new page

1. Create `src/pages/newpage.astro`
2. Import BaseLayout
3. Add content
4. Page will be available at `/newpage`

Example:
```astro
---
import BaseLayout from '../layouts/BaseLayout.astro';
---

<BaseLayout title="New Page">
  <div class="container">
    <h1>New Page</h1>
  </div>
</BaseLayout>
```

### Task: Add a new section to homepage

1. Open `src/pages/index.astro`
2. Add new section before footer:
```astro
<section class="section my-section">
  <div class="container">
    <div class="card fade-in">
      <h2>My Section</h2>
      <p>Content here</p>
    </div>
  </div>
</section>
```

3. Add styles in the `<style>` tag if needed

### Task: Change the accent color

1. Open `src/layouts/BaseLayout.astro`
2. Modify `--color-accent` and `--color-accent-bright`
3. Site updates automatically

### Task: Add animation to new element

1. Add `fade-in` class to element
2. Or create new animation in BaseLayout.astro:
```css
@keyframes slideIn {
  from { transform: translateX(-20px); opacity: 0; }
  to { transform: translateX(0); opacity: 1; }
}
.slide-in { animation: slideIn 0.6s ease-out; }
```

## Troubleshooting

### Build fails with TypeScript errors
- Check `tsconfig.json` extends correct config
- Ensure all props are properly typed in components

### Styles not applying
- Check if you need `is:global` on style tag
- Verify CSS custom properties are defined in BaseLayout

### Docker build fails
- Ensure `package.json` and `package-lock.json` are present
- Check Node version compatibility (needs 18+)

### Changes not showing in dev
- Hard refresh browser (Ctrl+Shift+R)
- Restart dev server
- Clear `.astro` cache directory

## Future Enhancements

Ideas for future development:
- [x] Add blog section using Astro's content collections
- [x] Create custom 404 page
- [ ] Add RSS feed for blog
- [ ] Create reusable components for service items
- [ ] Add more animations and transitions
- [ ] Integrate with analytics (privacy-friendly, self-hosted)

## Notes for AI Assistants

When working with this project:
1. Maintain the cozy aesthetic (warm colors, soft animations)
2. Keep the site lightweight and fast (static HTML/CSS)
3. Follow the existing component structure
4. Use CSS custom properties for theming
5. Ensure responsive design for mobile
6. Add appropriate TypeScript types when needed
7. Test both dev and production builds
8. Verify Docker build works after changes
