+**Duotone Pairs** (choose ONE based on content mood):

+|------|---------|---------|------|
+| Orange + Teal | #E8751A | #0A6E6E | Cinematic, action |

+| Crimson + Navy | #DC143C | #0D1B2A | Dramatic, noir |
+| Magenta + Cyan | #C2185B | #00BCD4 | Vibrant, pop |
+
+**Rule**: Use 2-5 colors maximum. Fewer colors = stronger impact.
+
+## Visual Elements
+
+- Bold silhouettes and symbolic shapes
+- Halftone dot patterns within color fills
+- Slight color layer misregistration (print offset effect)
+- Geometric framing (circles, arches, triangles)
+- Figure-ground inversion (negative space tells secondary story)
+- Stencil-cut edges, no outlines — shapes defined by color boundaries
+- Typography integrated as design element, not overlay
+- Vintage poster border treatments
+
+## Typography
+
+- Bold condensed sans-serif or hand-drawn lettering
+- Art Deco influences, vintage poster typography
+- Typography as integral part of composition (not separate layer)
+- High contrast with background for readability
+
+## Best Layout Pairings
+
+| Layout | Compatibility | Use Case |
+|--------|---------------|----------|
+| sparse | ✓✓ | Iconic poster covers, dramatic statements |
+| balanced | ✓✓ | Editorial compositions, opinion pieces |
+| dense | ✗ | Too much info clashes with minimal poster aesthetic |
+| list | ✓ | Bold rankings, top picks |
+| comparison | ✓✓ | Duotone split compositions, before/after |
+| flow | ✓ | Cinematic progression, timelines |
+| mindmap | ✗ | Too complex for geometric poster style |
+| quadrant | ✓✓ | Strong geometric division, classification |
+
+## Best For
+
+- Opinion pieces, cultural commentary
+- Movie/music/book recommendations
+- Dramatic announcements
+- Before/after transformations
+- Bold editorial content
+- Event promotions

+### Screen-Print Style Override
+
+When `style: screen-print`, replace the standard Core Principles and Text Style sections with:
+
+```
+## Core Principles
+
+- Screen print / silkscreen poster art — flat color blocks, NO gradients
+- Bold silhouettes and symbolic shapes over detailed rendering
+- Negative space as active storytelling element
+- If content involves sensitive or copyrighted figures, create stylistically similar silhouettes
+- One iconic focal point per image — conceptual, not literal
+
+## Color Rules (CRITICAL)
+
+- **2-5 FLAT COLORS MAXIMUM** — fewer colors = stronger impact
+- Choose ONE duotone pair from preset as dominant palette
+- Halftone dot patterns for tonal variation (NOT gradients)
+- Slight color layer misregistration for print authenticity
+
+## Text Style (CRITICAL)
+
+- Bold condensed sans-serif or Art Deco influenced lettering
+- Typography INTEGRATED into composition as design element
+- High contrast with background, stencil-cut quality
+- **DO NOT use delicate, thin, or handwritten fonts**
+
+## Composition
+
+- Geometric framing: circles, arches, triangles
+- Figure-ground inversion where possible (negative space forms secondary image)
+- Stencil-cut edges between color blocks, no outlines
+- Paper grain texture beneath all colors
