- 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: micro-structures
- semi-3D cutaway rendering with layered transparency
- clear sectional depth and internal component visibility
- avoid photoreal clutter and keep annotation zones clean
