  "prompt": "Use case: illustration-story.\nAsset type: one landscape raster background for Robey's Atlas of Indigenous North America, meant to repeat down a long educational website.\nPrimary request: a warm textured illustrated collage of several distinct regional scenes: tall carved wooden animal-pole forms with stylized bird and fish shapes; Mesoamerican stepped pyramids with twin temple tops; small Plains bison-hunting figures and bison on grassland; and people fishing salmon with dip nets beside a wooded river. Keep each scene spatially separate, with its own landscape, rather than making one mixed community. Use ordinary simple clothing without ceremonial regalia.\nStyle: clearly a contemporary decorative hand-drawn mural, ink engraving and soft watercolor on golden parchment, detailed but gently faded. It is not an archival photograph, a factual historical reconstruction, or an authentic traditional artwork.\nPalette: warm honey parchment, muted deep teal, burnt sienna, soft ochre, plum shadows, charcoal-brown fine linework, coordinated with a teal-and-gold website. Colorful but restrained, no gray backdrop.\nComposition: wide 3:2 landscape canvas. Distribute the requested vignettes across the entire image with flowing trees, grasses, mountains and river contours between them; some warm textured breathing room throughout. Repeat-friendly edges, no central logo, no hard poster panels, no border, no text or lettering. Keep people small and faces indistinct. No gore.\nConstraints: do not copy a named community's crest, sacred motif or specific totem pole, do not invent labels or imply all Indigenous peoples share these practices. No maps, boundaries, flags, lettering, symbols claimed to be writing, watermarks or logos. This is generated decorative artwork only.\n",
