Portrait de Bureau en Dessin au Trait et Aquarelle

Using the provided reference photo as the base, regenerate the exact same composition, pose, outfit, hair placement, and office setting, but transform it into a delicate Japanese-inspired [white-line drawing with light pale watercolor]. Keep the face anonymized with the same plain square mask. Use very fine graphite and ink contour lines, minimal shading, airy negative space, and a soft off-white textured paper background. Apply restrained, muted colors only on key areas such as the navy dress, white blouse, skin, and hair. Simplify the background into [minimal faint office line art], retaining the desk, computer monitor, window-side office atmosphere, and lamp silhouette. Color mood: [soft muted blue-gray and warm ivory].
