    "prompt": "Use case: stylized-concept. Create ONE new painterly atmosphere layer for stampede's brand guide. The three input images are the owner's preferred STYLE REFERENCES, not edit targets: valley for colour and painterly depth, marsh for huge quiet sky, mesa for understated terrain. Match their exact understated, hand-painted, luminous antique atmosphere.\n\nBegin from this reference's recipe: a nineteenth century American Luminist oil sketch on board, a wide valley at golden hour, low rolling hills in warm ochre and sage receding into haze, a thread of river catching the light, the upper half a wide empty luminous pale gold sky with no cloud detail, extremely muted desaturated palette, soft atmospheric perspective, visible board texture, calm and still.\n\nCompose a new WIDE 16:9 valley painting. Terrain and river belong entirely in the BOTTOM 35 PERCENT, lower than reference 1. Two low hills enter from the lower corners and open toward a distant luminous valley; a narrow pale river curves through that low valley. The UPPER 60 PERCENT is a broad unbroken pale cream-gold atmospheric wash, like reference 2, reserved for sharp UI that will be composited later. Fine matte oil-and-gouache-like brushwork, feathered edges, subtle board grain. Luminous, not muddy or brown. Very restrained warm straw, grey sage and pale mineral tones. Soft painted distances with finely resolved brush texture. Entirely uninhabited landscape. Full bleed painting continuing beyond all four edges.\n\nDo not paint any text, signature, seal, people, faces, buildings, logos, UI, panels, border, mount, frame or visible paper edges. No visible sun disc or theatrical sunbeams. No photographic look, glossy CGI, vector shapes, dramatic foreground objects or detailed clouds. One image only, not a sheet or collage. Output landscape 16:9, ideally 3840x2160 if supported.",
