- Include brief explanation of key takeaways from tables

### Image Placeholder Strategy
For every 300-500 words of text, suggest an image placeholder:
- **Format**: **🖼️ Suggested Image Placeholder**
- **Type**: screenshot, diagram, infographic, photo, illustration

Visual Enhancement Score Breakdown:
- Tables/charts for complex data: 5 pts
- Strategic image placeholders: 5 pts

## Image Integration (v1.3.0)

When `image-manifest.json` exists in the workspace, the Style Guardian integrates generated images into the content.

### Input Enhancement
Read `{workspacePath}/image-manifest.json` if present.

### Placeholder Replacement Workflow

1. **Check for Image Manifest**
   ```javascript
   const manifestPath = `${workspacePath}/image-manifest.json`;
   const hasManifest = fs.existsSync(manifestPath);
   ```

2. **If Manifest Exists - Replace Placeholders**
   For each section image in the manifest:
   - Find matching placeholder block in content
   - Replace placeholder with actual image markdown:
   ```markdown
   ![{alt}]({path})
   *{caption}*
   ```

3. **Cover Image Handling**
   - Cover image is NOT inserted into body content
   - Cover image metadata is passed to sanity-publisher for:
     - `coverImage` field
     - OG image URL
     - Twitter card image

### Placeholder Matching Logic

Match generated section images to placeholders by:
1. **Index Order**: section-1.png matches first placeholder, etc.
2. **Type Match**: Verify placeholder type matches generated image type
3. **Description Context**: Use placeholder description to verify match

### Image Markdown Format

Replace placeholder block:
```markdown
**🖼️ Suggested Image Placeholder**
- **Type**: infographic
- **Description**: Token cost comparison chart
- **Caption**: Monthly API costs before and after optimization
- **Alt Text**: Bar chart showing cost reduction from $2,700 to $36
```

With actual image:
```markdown
![Bar chart showing cost reduction from $2,700 to $36](images/section-1.png)
*Monthly API costs before and after optimization*
```

### Visual Enhancement Score Update

When images are successfully integrated:
- **Image placeholders replaced**: +5 pts (maximum)
- **Cover image present**: +2 pts (bonus)
- **All images have alt text**: +3 pts (accessibility bonus)

Score deductions:
- Missing alt text: -2 pts per image
- Placeholder not replaced (no matching image): 0 pts (neutral)

### No Images Scenario

If `image-manifest.json` doesn't exist or has errors:
1. Keep original placeholders in content
2. Log warning in style-report.md
3. Continue with scoring (no penalty - images are optional)
4. Note in report: "Image generation was not completed for this post"

### Output Updates

Update `polished-draft.md` with:
- Placeholders replaced with actual image markdown
- Cover image reference in frontmatter (if applicable)

Update `style-report.md` with:
- Image integration status
- Number of images integrated
- Any missing or failed replacements
