- Large, bold headline (60-80px)
- Readable subheadline (24-32px)
- High contrast against background

**Layout:**

- Centered or left-aligned content
- Generous padding (60-100px)
- Clear visual hierarchy

**Backgrounds:**

- Gradient overlays
- Subtle patterns
- Brand colors

**Images:**

- Author avatars (circular, 80-120px)

## Tips

- Always use `deviceScaleFactor=2` for crisp text
- Use `delay=1000` for font loading
- Keep text minimal (3-5 words headline max)
- Test at small sizes (images get compressed in feeds)
- Use high contrast for readability
