Anime Girl in Overgrown Mountain Garden

Create a vertical anime-style illustration of {argument name="character name" default="Kaga Sumire"}, a petite young girl sitting on sunlit stone steps in an overgrown mountain garden. She has short bobbed {argument name="hair color" default="silvery white hair"} with soft bangs, teal-blue eyes, and a small purple flower hairpin on the side of her head. She wears a loose plain white T-shirt tucked into high-waisted charcoal-gray cropped pants with a black belt, white ankle socks, and white sneakers. Pose her seated casually on the steps with one knee raised, one hand resting near her cheek in a thoughtful cute gesture, and the other hand beside a woven basket planter filled with green shoots. The setting is an old terraced stone ruin or garden stairway covered with lush ivy, vines, grasses, and small white wildflowers; include exactly one wicker basket planter, one visible purple hair flower, and a broad wall of heart-shaped ivy leaves climbing up the right side. Behind her, show layered stone terraces with dangling vines, evergreen trees, misty blue mountains, and a pale warm sky with soft clouds. Use golden-hour sunlight from the upper left, strong rim lighting on leaves and hair, long soft shadows, warm highlights, cool blue-green distant haze, delicate linework, rich cel-shaded anime rendering, cinematic composition, peaceful nostalgic mood, highly detailed foliage and masonry, no text, no watermark.
