Minimalistisches Aquarell-Linienporträt im Büro

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].
