## Best Practices

### Screenshot Design
- **Safe Zones**: Keep important content away from edges - avoid top 20% for status bar area
- **Text Hierarchy**: Use large, readable headlines (minimum 40pt equivalent)
- **Device Frames**: Use current-generation device mockups (iPhone 15 Pro, Pixel 8)
- **Contrast**: Ensure text is readable over any background elements
- **Consistency**: Maintain same style, fonts, and color scheme across all screenshots

### App Store Optimization
- **First Screenshot**: Make it your strongest - it's often the only one users see
- **Feature Callouts**: Highlight 1-2 key features per screenshot
- **Localization**: Translate all text for target markets, not just headlines
- **Seasonal Updates**: Refresh screenshots for major app updates

### iPad Screenshots
- **Landscape Option**: iPad supports landscape screenshots for certain apps
- **Utilize Space**: Take advantage of larger canvas for more detailed UI
- **Split View**: Show multitasking capabilities if applicable

## Mode Selection

Ask your users before generating:

**"Do you want fast drafts for iteration, or final quality for submission?"**

| Mode | Best For | Speed | Quality |
|------|----------|-------|---------|
| `max` | Final App Store submission, polished assets | Slower | Highest |
| `eco` | Quick drafts, A/B test variations, concept exploration | Faster | Good |

## Multi-Turn Screenshot Iteration

Use `session_id` to iterate on screenshot designs:

```bash
# Initial screenshot
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Create an iPhone App Store screenshot at 1320x2868 for a podcast app with episode list view",
    "session_id": "podcast-screenshot-v1"
  }'

# Iterate based on feedback
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Add a headline saying \"Your Daily Commute Companion\" and change the background to a gradient purple",
    "session_id": "podcast-screenshot-v1"
  }'

# Request variation

  -d '{
    "message": "Create 2 more variations with different headline angles - one focusing on discovery, one on offline listening",
    "session_id": "podcast-screenshot-v1"
  }'
```

## iPad Screenshot Generation

```bash
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
