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 fairy-tale style, shaped like the entrance to a tiny ice hut (ledyanaya izbushka) — translucent blue ice with carved frost patterns, snowflake ornaments, and silver sparkling details. The door has a rounded arch top, decorative wrought-iron hinges shaped like ice crystals, a carved icy frame with geometric patterns, and a small round window with a lattice of frost. A brass ring handle in the shape of a tiny horseshoe, frozen into the ice. 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.
