5-stage horizontal manufacturing timeline, frozen mid-assembly. deep matte black background. dramatic industrial spotlights, deep shadow falloff. S1: Components scattered, floating, zero assembly. S2: Converging with speed lines, skeleton emerging. S3: Half-built, peak tension, fasteners mid-tighten. S4: Chassis open, full internals exposed. S5: Finished product + ghost wireframe overlay. Same 3/4 camera angle across all stages. Dotted trajectory arcs connect each component across stages. Each component color-coded consistently.
