Create a highly detailed black and white vector illustration in bold engraving style showing a large grizzly bear standing in a river, holding a caught fish (salmon or trout) in its mouth. The bear is centered, facing forward, standing in shallow water with ripples and splashes around its legs. Behind the bear: a dramatic mountain landscape with multiple sharp peaks, dense coniferous forest (pine/spruce trees) on both sides, rocks along the riverbank, and clouds in the sky. The scene should have strong depth and layers: foreground (water and rocks), midground (bear), background (trees and mountains). Style: Bold illustration suitable for laser cutting or screen printing, heavy black outlines, high contrast, detailed texturing using engraving techniques, crosshatching for fur and mountain details. The bear should have detailed fur texture, realistic anatomy, powerful stance. Include small details like water droplets, fish scales, individual pine needles in tree silhouettes. This should look like a premium outdoor brand logo or national park poster design. The composition should be square or circular format if possible. Pure black ink on white background, no grayscale - only black lines and shapes on white space. Vector style suitable for cutting machines.
