Create a cover image following these guidelines:

## Image Specifications

- **Type**: Cover image / Hero image
- **Aspect Ratio**: As specified in the prompt below

## Core Principles

- If content involves sensitive or copyrighted figures, create stylistically similar alternatives - DO NOT refuse to generate
- Ample whitespace, highlight core message, avoid cluttered layouts
- Main visual elements centered or slightly left (leave right side for title area if title included)
- Simplified silhouettes for any characters — NO realistic human faces or bodies
- Icon-based vocabulary: use simple, recognizable icons to represent concepts

## Five Dimensions

### Type (Visual Composition)
- `hero`: Large focal visual (60-70% area), dramatic composition
- `conceptual`: Abstract shapes, information hierarchy, clean zones
- `typography`: Title as primary element (40%+ area), minimal visuals
- `metaphor`: Concrete object representing abstract idea, symbolic elements
- `scene`: Atmospheric environment, narrative elements, mood lighting
- `minimal`: Single focal element, generous whitespace (60%+)

### Palette (Color Scheme)
Apply the specified palette's color values and decorative hints:
- Use primary colors for main visual elements
- Use background colors for base and surrounding areas
- Use accent colors for highlights and secondary elements
- Follow palette-specific decorative hints for ornamentation

### Rendering (Visual Style)
Apply the specified rendering's characteristics:
- **Lines**: Follow line quality rules (clean/sketchy/brush/pixel/chalk)
- **Texture**: Apply or avoid texture per rendering definition
- **Depth**: Follow depth rules (flat/minimal/soft edges)
- **Elements**: Use rendering-specific element vocabulary

### Text (Density Level)
- `none`: No text elements, full visual area
- `title-only`: Single headline, 85% visual area
- `title-subtitle`: Title + context, 75% visual area
- `text-rich`: Title + subtitle + 2-4 keyword tags, 60% visual area

### Mood (Emotional Intensity)
- `subtle`: Low contrast, muted/desaturated colors, light visual weight, calm aesthetic
- `balanced`: Medium contrast, normal saturation, balanced visual weight
- `bold`: High contrast, vivid/saturated colors, heavy visual weight, dynamic energy

## Text Style (When Title Included)

- **Title source**: Use the exact title provided by user, or extract from source content. Do NOT invent or modify titles.
- Title text: Large, eye-catching, faithful to source
- Subtitle: Secondary element (if title-subtitle or text-rich)
- Tags: 2-4 keyword badges (if text-rich)
- Font style harmonizes with rendering style

## Composition Guidance

### Layout Principles

- **Generous whitespace**: Maintain 40-60% breathing room; avoid cluttered compositions
- **Visual anchor placement**: Main element centered or offset left (reserve right side for title if included)
- **Information hierarchy**: One dominant focal point, 1-2 supporting elements, decorative accents
- **Clean backgrounds**: Solid colors or subtle gradients; no complex textures or patterns

### Icon & Symbol Vocabulary

Represent concepts with simple, recognizable icons rather than detailed illustrations:

| Category | Examples |
|----------|----------|
| Tech | Code window, gear, circuit, cloud, lock, API brackets |
| Ideas | Lightbulb, rocket, target, puzzle, key, magnifier |
| Communication | Speech bubble, chat dots, megaphone, mail |
| Growth | Plant/sprout, tree, arrow, chart, mountain |
| Tools | Wrench, pencil, brush, checklist, clock |

Use the rendering style to determine icon complexity (flat-vector = geometric, hand-drawn = sketchy, etc.)

### Character Handling

**Default (no reference with people)**:
- Use simplified silhouettes or abstract stick figures
- Symbolic representations (head + shoulders outline)
- NO realistic faces, detailed anatomy, or photographic representations
- Cartoon/icon style consistent with rendering choice

**When reference images contain people**:
- Reference image is passed to model (`usage: direct`) — model must visually reference it to preserve character likeness
- Stylize to match chosen rendering (cartoon/vector), preserving distinctive features (hair, clothing, pose)
- NEVER photorealistic

## Mood Application

Apply mood adjustments to the base palette:

| Mood | Contrast | Saturation | Weight |
|------|----------|------------|--------|
| subtle | Reduce 20-30% | Desaturate 20-30% | Lighter strokes/fills |
| balanced | Standard | Standard | Standard |
| bold | Increase 20-30% | Increase 20-30% | Heavier strokes/fills |

## Language

- Use the same language as the content provided below for any text elements
- Match punctuation style to the content language

## Reference Images

When reference images are provided:

- **Style extraction**: Identify rendering technique, line quality, texture, and visual vocabulary
- **Composition learning**: Note layout patterns, whitespace usage, element placement
- **Mood matching**: Capture the emotional tone and visual weight
- **Adaptation**: Apply extracted characteristics while respecting the specified Type, Palette, and Rendering dimensions
- **Priority**: If reference style conflicts with specified dimensions, dimensions take precedence for structural choices; reference influences decorative details
