## Content-Driven Design

- Article title and summary inform the visual metaphor choice
- Keywords guide decorative elements and symbols
- The skill controls visual style; the content drives meaning

## Type-Specific Composition

| Type | Composition Guidelines |
|------|------------------------|
| `hero` | Large focal visual (60-70% area), title overlay on visual, dramatic composition |
| `conceptual` | Abstract shapes representing core concepts, information hierarchy, clean zones |
| `typography` | Title as primary element (40%+ area), minimal supporting visuals, strong hierarchy |
| `metaphor` | Concrete object/scene representing abstract idea, symbolic elements, emotional resonance |
| `scene` | Atmospheric environment, narrative elements, mood-setting lighting and colors |
| `minimal` | Single focal element, generous whitespace (60%+), essential shapes only |

## Title Guidelines

When text level includes title:
- Max 8 characters, punchy headline
- Use engagement hooks: numbers ("3个陷阱"), questions ("Why X?"), contrasts ("A vs B"), pain points ("别再X了")
- Match confirmed language

## Watermark Application

If enabled in preferences, add to prompt:

```
Include a subtle watermark "[content]" positioned at [position].
The watermark should be legible but not distracting from the main content.
```
