Create a minimalist cartoon illustration in vector style, depicting a cozy interior of a small house. The composition should be empty: there are no people, animals, or other characters inside. The design is executed in a flat vector style using simple geometric shapes and a pastel color palette. Add soft gradient shadows and delicate highlights to give the objects slight volume, maintaining the overall flat aesthetic. The background should remain clean and vector. The image should be neat, symmetrical, with clear lines and stylistic balance.
