Create a horizontal 16:9 retro engineering exploded-view illustration of a Zhuge repeating crossbow as a non-functional museum-style educational artifact diagram. Show the wooden body, bow arms, string, bolt magazine, feeding mechanism, lever assembly, trigger lever, wooden frame, and stock separated in a clean exploded layout with dotted guide lines. Use an aged parchment background, hand-drawn sepia ink linework, lightly shaded wood grain, antique Chinese border ornaments, and a large brush-calligraphy Chinese title at the top. Add concise Chinese component labels with thin leader lines, designed as readable display labels rather than precise manufacturing dimensions. Keep the layout elegant, historical, educational, and decorative, like a retro exhibit poster or ancient engineering notebook page. Avoid modern weapons, realistic firing action, assembly instructions, exact measurements, dangerous operational detail, real logos, cluttered text, distorted perspective, and low-resolution artifacts.
