## Prompt Structure

Effective prompts follow this pattern:

```
[Subject] [Style] [Background] [Constraints]
```

**Key principles:**
- Be specific about what you want
- Specify background type for easier post-processing
- Include negative constraints ("no text", "no labels")
- Describe composition ("centered", "full body")
