Duotone Botanical Seamless Patterns

Create seamless, vintage-inspired botanical patterns with precise vector-style linework. This prompt produces dense, interlocking designs with clean outer contours, fine hatching, and stippling textures. The result features a smooth, flat duotone color palette (off-white on charcoal-blue), evoking retro screen-print or risograph aesthetics. Perfect for textiles, wallpapers and digital backgrounds.
