Bande dessinée / Storyboard - Watercolor Anime Café Colorization

Using REFERENCE_0 as the exact line-art base, colorize the illustration into a richly detailed hand-painted watercolor/gouache anime illustration. Preserve the original composition, perspective, character pose, café setting, furniture, bookshelves, window, plants, food, and all line details, but replace the grayscale pencil look with warm natural colors and painterly texture. Use a cozy vintage café palette: honey-brown wood, cream and gold kimono fabric, blonde hair, blue and multicolored books, green foliage, yellow flowers, warm pendant lights, coffee and pastries. Keep the masked face area as a flat plain rectangle with no facial features. Add depth through soft sunlight from the window, gentle highlights on glass and porcelain, layered shadows, visible brush strokes, and high-detail color accents while maintaining the delicate original linework.
