# Article Cover SVG Generation

Generate professional, visually striking article cover images in SVG format for technical blogs, documentation, and articles.

## Critical Rules

1. **ViewBox Standard**: Use `viewBox="0 0 1200 630"` (social media friendly 1.91:1 ratio)

2. **Text Readability (MUST follow)**:
   - Main title: 44-48px, bold, high contrast
   - Subtitle: 28-32px, white or light color
   - Labels/tags: 14-16px
   - Never use fonts smaller than 11px

3. **Background Design**:
   - Always use gradient backgrounds (avoid flat solid colors)
   - Dark tech themes: `#0d1117` → `#161b22` (GitHub dark style)
   - Add subtle grid patterns or decorative elements for depth

4. **Visual Hierarchy**:
   - Title area: bottom 1/3 of the image (y: 420-540)
   - Diagram/illustration area: top 2/3 (y: 80-400)
   - Tags/labels: bottom edge (y: 550-600)

5. **Color Contrast**: Ensure text is readable against backgrounds
   - Light text on dark backgrounds
   - Use gradients for emphasis (orange/yellow for tech, blue/cyan for data)

## Design Patterns

### Tech Article Cover (Comparison Layout)
Best for: Performance comparisons, version upgrades, before/after scenarios

```

## Workflow

1. **Understand the article**: What's the main topic? Is it a comparison, tutorial, or overview?

2. **Choose layout pattern**:
   - Comparison → Use 2-3 column comparison layout
   - Process/Flow → Use flow diagram layout
   - Single concept → Use centered illustration

3. **Extract key elements**:
   - Main title (keep concise, 10-15 Chinese chars or 5-8 English words)
   - Subtitle (descriptive, can be longer)
   - Key metrics (performance numbers, version info)
   - Tags (3-5 relevant keywords)

4. **Design the illustration**:
   - Use simple shapes (rectangles, arrows)
   - Show the core concept visually
   - Use color to differentiate states/versions

5. **Generate SVG**: Follow the template, ensure all text is readable

## Output

- Filename: `{article-slug}-cover.svg`
- Location: Same directory as the article or `assets/` folder
- Tell user: Can be opened in browser, converted to PNG via Inkscape/browser screenshot

## Tips

- **Chinese text**: Use `font-family="Arial, sans-serif"` which has good CJK support
- **Emphasis**: Use `filter="url(#glow)"` sparingly on key elements
- **Spacing**: Keep 20-40px padding around text elements
- **Testing**: Open SVG in browser to verify rendering before finalizing
