Isometric Cross-Section Illustration of a Floating Modular Apartment Building

A detailed prompt for generating a 2.5D isometric cross-section illustration of a multi-level modular apartment building floating against a starry night sky. The prompt meticulously describes the contents of each level (music room, living room, kitchen, gym, bedroom), the lighting (warm amber glow contrasting with deep midnight blue), and the desired art style (flat vector, geometric lines, Behance style, orthographic view).
