Vertical illustration in classic Disney 2D animation style (Golden Age Disney), soft rounded shapes, gentle linework, vibrant watercolor-like coloring, whimsical and charming design. A closed wooden arched door in Russian folk style, decorated with intricate frost patterns — delicate white and silver ice crystals, snowflakes, and swirling frosty vines painted or carved into the wood. The door has a rounded arch top, decorative wrought-iron hinges, a carved wooden frame with geometric patterns, and a small round window with a lattice covered in frost. A brass ring handle in the shape of a tiny horseshoe. The door is fully closed. Clean pure white background, isolated object, no scenery, no burrow interior, no background elements. Vertical portrait orientation, 2:3 aspect ratio.
