A Little Robot Under the Wisteria

Generate exactly one finished image, never a collage, grid, or multiple variants. Original cheerful retro science-fiction anime scene with rounded graphic shapes, precise mechanical linework and flat pastel color blocks. The main subject is a small friendly box-shaped mint service robot carefully pouring tea for a 70-year-old woman gardener with a silver cropped haircut, round glasses and a broad relaxed face under a wisteria canopy. One coherent pouring stream into a cup, robot joint construction clear, daylight filtered through violet flowers, rich hand-painted foliage, quiet humor and relaxed human expression. Square, no text. Original visual concept, carefully resolved composition and materials. No watermark. Text-to-image only; do not use previous conversation images as visual inputs.
