I've collected multiple Facebook ads for the same offer. Help me identify what messages and angles consistently convert.

Analyse across all ads:

1. Message Patterns
- What pain points appear most frequently?
- Which promises are in every ad?
- What words/phrases repeat?
- How do they describe the transformation?

2. Angle Variations
- Different ways they position the same offer
- Which demographics get which message
- Emotional triggers by audience
- Authority vs empathy positioning

3. Visual Intelligence
- What types of images/videos persist
- Color schemes and design patterns
- Text overlay strategies
- Social proof presentation

4. Pre-Frame Analysis
- How do they set expectations?
- What beliefs do they challenge?
- How do they qualify prospects?
- What do they promise before the click?

Identify their "control" - the core message that appears across variations. Then show how they adapt it for different angles.
