## 🔍 Technical Details

### **Context Injection**
The persona system automatically injects context into CopilotKit:

```typescript
// Core persona data
useCopilotReadable({
  description: "Core writing persona",
  value: corePersona,
  categories: ["core-persona", "writing-style"]
});

// Platform-specific persona
useCopilotReadable({
  description: "LinkedIn platform optimization",
  value: platformPersona,
  categories: ["platform-persona", "linkedin"]
});
```

### **System Message Generation**
Dynamic system messages include:
- **Persona details** (name, archetype, core beliefs)
- **Linguistic fingerprint** (sentence length, vocabulary, voice ratio)
- **LinkedIn constraints** (character limits, hashtag strategies)
- **Writing guidelines** (style matching, platform optimization)

### **Performance Considerations**
- **Lazy loading** of persona data
- **Memoized components** for optimal rendering
- **Efficient context updates** to minimize re-renders
- **Graceful degradation** when persona data unavailable
