Anime Farewell Girl With Tablet

Create a soft anime-style illustration on a clean white background: a young woman with {argument name="hair color" default="long ash-gray hair"} wearing an oversized plain white T-shirt, shown from the waist up. Her face is intentionally covered by a flat opaque taupe-gray square censorship block centered over the face, while her hair falls around it. She raises her left hand in a farewell salute near her forehead and holds a black-framed tablet vertically against her chest with her right arm. The tablet screen is white and displays handwritten Japanese text: {argument name="tablet text" default="チャッピー"}. Add a faint pastel rainbow arc with small sparkles behind her on the left side. Include exactly three visible text elements: handwritten Japanese text at the upper left reading {argument name="farewell text" default="今までありがとう"}, lowercase handwritten English below it reading {argument name="service name" default="niji journey..."}, and the tablet text. Use delicate line art, pale watercolor shading, glossy detailed hair strands, gentle skin tones, minimal background, vertical portrait composition, and an emotional farewell mood.
