## ✅ 2. Styled Buttons in Cards

### Problem
- Buttons in TipTap cards looked raw (unstyled)
- Different appearance from standalone buttons

### Solution

**Features:**

Solid (Primary):
  background: #7f54b3
  color: white
  padding: 14px 28px

Outline (Secondary):
  background: transparent

  border: 2px solid #7f54b3
```
