Интерактивная 3D-выставка реакторного здания с 26 слоями систем

Build an interactive 3D web exhibit of a nuclear power plant reactor building that visitors can explore. Model the structure from many small parts: reactor core with fuel channels, steam drums, pipes, turbine hall, frames and walls. Add a side panel with toggles to show or hide about two dozen systems, plus a slider that pulls the power block apart layer by layer into an exploded view. Include three modes: a plant view, a reactor close-up and a schematic titled around turning heat into motion that shows the loop from reactor to steam, turbine and generator. Animate steam flow, water movement and a spinning turbine. Use a clean light technical style with thin dark lines and a restrained palette, and a dark variant for the schematic mode. Orbit camera with labels on hover. Done means every system toggles correctly, the exploded view is smooth and the animations run in real time in the browser.
