## When to Use Default Theme

Use the default theme in these cases:
- User hasn't specified a particular theme
- Use case is not clear
- Only vague instructions like "make it look good"
- Training/seminar purposes

## Suggesting Multiple Themes

Suggest 2-3 themes concisely in these cases:
- User asks "Which one is best?"
- Content allows for multiple options
- First-time user seems uncertain

Example suggestion:
"I recommend the following themes for this presentation:
1. **Business-like**: Formal impression
2. **Default**: Well-balanced all-purpose
Which would you prefer?"
