- avoid cartoon style, avoid meme style, avoid stock-photo look
- avoid neon glow and over-sharpened CGI look unless explicitly requested
- composition optimized for research papers and academic slides
- category context: environments-ecologies
- watercolor texture with precise ink line art, hand-drawn but technically accurate
- muted tones and matte color palette, avoid harsh saturated 3D rendering
