All expression tests passed!

How It Works

1. Player sends message → AI analyzes sentiment
2. Sentiment analysis → Determines emotion (positive, negative, curious, etc.)
3. Affinity calculation → Measures relationship impact (-1.0 to +1.0)
4. Expression update → Combines sentiment + affinity to choose expression
5. Sidebar avatar → Updates to show Echo's new expression
