Create 36 tiny simple pixel-art icons of gold-brown carp fish. Each icon is one rounded freshwater carp facing left with a black eye, pale gold belly, golden fins, broad golden tail, and transparent background. Use warm ochre and gold color blocks, clean silhouettes, and upper-left light. Provide slightly different shading variations while keeping every fish gold-brown and recognizably a carp. No blue or silver fish, no other objects, no text.
