Generation Tips

1. Diagrams: Use "clean infographic style", "technical illustration", "minimal diagram" in prompts
2. Photos: Use "product photography", "professional shot", "realistic" for hardware images
3. Concepts: Use "visualization", "abstract representation" for abstract ideas
4. Logos: Consider downloading official logos instead of generating (better accuracy)
5. Consistency: Add "educational style", "professional presentation" to maintain visual coherence
