Use case: precise-object-edit / stylized-concept. Create ONE 1536x1024 landscape room concept. The supplied image is the canonical Ranch On Air room to customize. Preserve the straight-on front elevation, single flat back wall, exact broad layout, room proportions, window slot upper right, storage slot left, desk central, chair center and pet corner lower right. Preserve the polished hand-painted 2D cozy game illustration style and coherent scale. This is a furnishing/progression variation of the SAME customizable room. No isometric room, no side walls, no 3D renderer look, no app UI, no text labels, no logos. Avoid large shifts in camera or furniture overlap. Make this the City Signals theme. Change the one flat back wall to softly weathered warm red brick with dark teal timber trim, no side walls. A slim but substantial walnut desk on cream metal drawers, caramel-brown upholstered chair, warm matte-black architect lamp. Central compact amateur radio with luminous cyan panel, neatly placed small portable receiver, headphones and tabletop mic; no computer-screen wall. Left storage shelf becomes blackened-steel and wood with carefully arranged books, portable field case, succulent and woven basket. An artfully ordered contact-card pinboard and a simple city map. Right window shows a calm dusk city skyline with rooftop antenna silhouettes and a glowing orange horizon. A muted teal geometric rug, ceramic ochre mug, low lower-right pet cushion with a curled orange tabby. Sophisticated small-apartment radio refuge, warm tactile objects and usable negative space, no nightclub colors. Return only the full room artwork.
