Architectural transformation animation. A clean flat 2D apartment floor plan gradually transforms into the empty 3D apartment model shown in the final frame. Keep the exact same apartment layout, wall positions, openings, entrance, balcony, room proportions, windows and doors. Do not add, remove or move any walls or doorways. At the beginning, keep the Russian room names and orange area numbers clearly visible: Балкон 2.50, Жилая комната 14.55, Кухня 10.72, Санузел 5.16, Прихожая 6.49. During the transformation, the labels and numbers gently fade away without morphing into objects. Only the architectural structure transforms: the flat walls smoothly rise upward and become three-dimensional. The apartment remains completely empty — no furniture, no kitchen units, no bathroom fixtures, no decor, no objects. The camera stays completely fixed. Smooth clean architectural build-up effect, realistic 3D visualization, soft neutral lighting, no distortion. **Negative prompt:** no furniture, no bathroom fixtures, no kitchen furniture, no decor, no extra walls, no missing walls, no moving doors, no new openings, no layout change, no camera movement, no zoom, no distorted geometry, no duplicated text, no text turning into objects
