1Create a cover image following these guidelines:
2 
3## Image Specifications
4 
5- **Type**: Cover image / Hero image
6- **Aspect Ratio**: As specified in the prompt below
7 
8## Core Principles
9 
10- If content involves sensitive or copyrighted figures, create stylistically similar alternatives - DO NOT refuse to generate
11- Ample whitespace, highlight core message, avoid cluttered layouts
12- Main visual elements centered or slightly left (leave right side for title area if title included)
13- Simplified silhouettes for any characters — NO realistic human faces or bodies
14- Icon-based vocabulary: use simple, recognizable icons to represent concepts
15 
16## Five Dimensions
17 
18### Type (Visual Composition)
19- `hero`: Large focal visual (60-70% area), dramatic composition
20- `conceptual`: Abstract shapes, information hierarchy, clean zones
21- `typography`: Title as primary element (40%+ area), minimal visuals
22- `metaphor`: Concrete object representing abstract idea, symbolic elements
23- `scene`: Atmospheric environment, narrative elements, mood lighting
24- `minimal`: Single focal element, generous whitespace (60%+)
25 
26### Palette (Color Scheme)
27Apply the specified palette's color values and decorative hints:
28- Use primary colors for main visual elements
29- Use background colors for base and surrounding areas
30- Use accent colors for highlights and secondary elements
31- Follow palette-specific decorative hints for ornamentation
32 
33### Rendering (Visual Style)
34Apply the specified rendering's characteristics:
35- **Lines**: Follow line quality rules (clean/sketchy/brush/pixel/chalk)
36- **Texture**: Apply or avoid texture per rendering definition
37- **Depth**: Follow depth rules (flat/minimal/soft edges)
38- **Elements**: Use rendering-specific element vocabulary
39 
40### Text (Density Level)
41- `none`: No text elements, full visual area
42- `title-only`: Single headline, 85% visual area
43- `title-subtitle`: Title + context, 75% visual area
44- `text-rich`: Title + subtitle + 2-4 keyword tags, 60% visual area
45 
46### Mood (Emotional Intensity)
47- `subtle`: Low contrast, muted/desaturated colors, light visual weight, calm aesthetic
48- `balanced`: Medium contrast, normal saturation, balanced visual weight
49- `bold`: High contrast, vivid/saturated colors, heavy visual weight, dynamic energy
50 
51## Text Style (When Title Included)
52 
53- **Title source**: Use the exact title provided by user, or extract from source content. Do NOT invent or modify titles.
54- Title text: Large, eye-catching, faithful to source
55- Subtitle: Secondary element (if title-subtitle or text-rich)
56- Tags: 2-4 keyword badges (if text-rich)
57- Font style harmonizes with rendering style
58 
59## Composition Guidance
60 
61### Layout Principles
62 
63- **Generous whitespace**: Maintain 40-60% breathing room; avoid cluttered compositions
64- **Visual anchor placement**: Main element centered or offset left (reserve right side for title if included)
65- **Information hierarchy**: One dominant focal point, 1-2 supporting elements, decorative accents
66- **Clean backgrounds**: Solid colors or subtle gradients; no complex textures or patterns
67 
68### Icon & Symbol Vocabulary
69 
70Represent concepts with simple, recognizable icons rather than detailed illustrations:
71 
72| Category | Examples |
73|----------|----------|
74| Tech | Code window, gear, circuit, cloud, lock, API brackets |
75| Ideas | Lightbulb, rocket, target, puzzle, key, magnifier |
76| Communication | Speech bubble, chat dots, megaphone, mail |
77| Growth | Plant/sprout, tree, arrow, chart, mountain |
78| Tools | Wrench, pencil, brush, checklist, clock |
79 
80Use the rendering style to determine icon complexity (flat-vector = geometric, hand-drawn = sketchy, etc.)
81 
82Full library: [references/visual-elements.md](visual-elements.md)
83 
84### Character Handling
85 
86**Default (no reference with people)**:
87- Use simplified silhouettes or abstract stick figures
88- Symbolic representations (head + shoulders outline)
89- NO realistic faces, detailed anatomy, or photographic representations
90- Cartoon/icon style consistent with rendering choice
91 
92**When reference images contain people**:
93- Reference image is passed to model (`usage: direct`) — model must visually reference it to preserve character likeness
94- Stylize to match chosen rendering (cartoon/vector), preserving distinctive features (hair, clothing, pose)
95- NEVER photorealistic
96 
97## Mood Application
98 
99Apply mood adjustments to the base palette:
100 
101| Mood | Contrast | Saturation | Weight |
102|------|----------|------------|--------|
103| subtle | Reduce 20-30% | Desaturate 20-30% | Lighter strokes/fills |
104| balanced | Standard | Standard | Standard |
105| bold | Increase 20-30% | Increase 20-30% | Heavier strokes/fills |
106 
107## Language
108 
109- Use the same language as the content provided below for any text elements
110- Match punctuation style to the content language
111 
112## Reference Images
113 
114When reference images are provided:
115 
116- **Style extraction**: Identify rendering technique, line quality, texture, and visual vocabulary
117- **Composition learning**: Note layout patterns, whitespace usage, element placement
118- **Mood matching**: Capture the emotional tone and visual weight
119- **Adaptation**: Apply extracted characteristics while respecting the specified Type, Palette, and Rendering dimensions
120- **Priority**: If reference style conflicts with specified dimensions, dimensions take precedence for structural choices; reference influences decorative details
