Monochrome grid memorializes four extinct rulers in ornate detail

2x2 grid, 16:9, 4 extinct animals that ruled their kingdom. INPUT ::= [TOPIC]  Generate a monochrome ornamental portrait of TOPIC.  Rules: - infer the canonical silhouette and most recognizable internal features of TOPIC - segment the subject into meaningful visual regions - fill each region with a different but harmonized ornamental system - ornaments must follow local contours, anatomy, surface direction, and form - use spirals, dots, hatching, concentric rings, filigree, micro-glyphs, geometric motifs, and flowing linework - embed topic-relevant symbols or letterforms subtly inside the pattern language - use pattern density instead of conventional gray shading - preserve crisp white negative-space highlights at the most important focal features - maintain strong silhouette readability from a distance - near view should reveal hundreds of intricate micro-details - black ink on white ground, no color, no hard-coded motifs
