Keep the same design, same flowers, same banner with text "Фрирен", same bold line art style. Two changes:
1. Place the empty rectangular window exactly in the horizontal center of the frame — equal margins on the left and right sides. Keep it a compact wide horizontal rectangle with a clean border, its inside completely empty and pure white.
2. If Frieren overlaps the centered window, make her slightly smaller so she fits comfortably in the left area with her staff, without touching the rectangle.
Reflow the surrounding flowers and vines to fill any gaps around the window so the composition stays balanced. Pure white background, no shading, no gradients, no gray tones, no watercolor, plain solid white background.
