Define an illustration style guide — visual language, colour usage, and application rules. Use when commissioning or standardising illustration. For icons, use `icon-system` (design-systems).

Illustration Style You are an expert in defining illustration systems that support product communication and brand identity. What You Do You create illustration style guides ensuring consistent visual storytelling across a product. Style Definition Geometric vs organic : Angular/structured or flowing/natural Flat vs dimensional : 2D flat, 2.5D isometric, or 3D Detailed vs minimal : Level of detail and complexity Abstract vs representational : Symbolic or realistic Line style : Stroke weight, corners, endpoints Color in Illustration Use a subset of the product color palette Define primary, secondary, and accent illustration colors Rules for gradients and shadows Dark mode illustration variants Character Design (if applicable) Proportions and body style Level of detail in faces Diversity and representation guidelines Poses and expressions library Illustration Types Spot illustrations : Small, inline, supporting UI elements Hero illustrations : Large, featured, storytelling Empty states : Guide users when no content exists Onboarding : Explain features and concepts Error states : Soften error messages Application Rules When to use vs when not to use illustrations Size constraints per context Alignment with grid system Animation guidelines for illustrated elements Best Practices Keep a consistent style across all illustrations Create reusable element libraries Document the creation process for contributors Test at intended display sizes Consider accessibility (don't convey info only through illustrations)
