## 3. Content Collections Schema
### Blog Posts
```typescript
// src/content/config.ts
const blog = defineCollection({
schema: z.object({
title: z.string(),
description: z.string(),
publishDate: z.date(),
author: z.string().default('David Aragón'),
tags: z.array(z.string()),
category: z.enum(['technical', 'business', 'personal']),
featured: z.boolean().default(false),
draft: z.boolean().default(false),
image: z.string().optional(),
}),
});
```

github: z.string().url().optional(),
status: z.enum(['active', 'development', 'completed']),
tags: z.array(z.string()),
startDate: z.date(),
featured: z.boolean().default(false),
image: z.string().optional(),
}),
});
```

## 4. Design System
### Color Palette (Dark Mode Optimized)
```css
/* Tailwind config */
colors: {
background: '#0a0e27', // Deep navy
surface: '#131729', // Card backgrounds
primary: '#60a5fa', // Blue accent
secondary: '#a78bfa', // Purple accent
text: {
primary: '#f1f5f9', // Light text
secondary: '#94a3b8', // Muted text
tertiary: '#64748b', // Subtle text
},
accent: {
green: '#34d399', // Success
red: '#f87171', // Error
yellow: '#fbbf24', // Warning
}
}
```
### Typography
- **Headings**: Inter (font-weight: 600-800)
- **Body**: Inter (font-weight: 400-500)
- **Code**: JetBrains Mono (font-weight: 400)
- **Scale**:
- H1: 3rem (48px)
- H2: 2.25rem (36px)
- H3: 1.875rem (30px)
- Body: 1rem (16px)
- Small: 0.875rem (14px)
### Component System
- **Cards**: Glassmorphism effect with subtle backdrop blur
- **Buttons**: Hover transitions, focus states
- **Navigation**: Sticky header with scroll-based styling
- **Links**: Underline on hover, smooth transitions
- **Code blocks**: Syntax highlighting with Shiki (VS Code Dark+ theme)

## 6. Docker Deployment Architecture
### Multi-Stage Dockerfile
```dockerfile
# Stage 1: Build
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build
# Stage 2: Serve
FROM nginx:alpine
COPY --from=builder /app/dist /usr/share/nginx/html
COPY .docker/nginx.conf /etc/nginx/nginx.conf
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
```
### Nginx Configuration
- Serve static files from `/usr/share/nginx/html`
- Gzip compression for text assets
- Cache-Control headers (1 year for assets, 1 hour for HTML)
- 404 fallback to custom 404.html
- Security headers (CSP, X-Frame-Options, etc.)
### Docker Compose (Portainer Stack)
```yaml
version: '3.8'
services:
portfolio:
build:
context: .
dockerfile: .docker/Dockerfile
container_name: davidaragon-portfolio
restart: unless-stopped
ports:
- "3010:80"
environment:
- NODE_ENV=production
labels:
- "traefik.enable=true"
- "traefik.http.routers.portfolio.rule=Host(`davidaragon.impresion3d.pro`)"
- "traefik.http.services.portfolio.loadbalancer.server.port=80"
```
### Deployment on 192.168.1.30
1. **Portainer stack deployment**:
- Create new stack "davidaragon-portfolio"
- Upload docker-compose.yml
- Configure environment variables
- Deploy stack
2. **Domain configuration**:
- DNS A record: `davidaragon.impresion3d.pro` → 192.168.1.30
- Traefik reverse proxy for HTTPS
- Let's Encrypt SSL certificate
3. **CI/CD (future)**:
- Gitea Actions on push to main branch
- Build Docker image
- Push to local registry or rebuild on server
- Portainer webhook to redeploy stack
