+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.)
+
+Full library: [references/visual-elements.md](visual-elements.md)
+
+### 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
