Create a dramatic evolutionary timeline showing 5 generations of [$SUBJECT_DOMAIN] ascending diagonally across the canvas like architectural steps. Each generation occupies its own elevated platform: Generation 1 (1900s-era, lower-left) through Generation 5 (cutting-edge, upper-right). Render each machine as a museum-quality cutaway revealing internal mechanisms, with transparent acrylic cross-sections. The older generations display sepia-toned patina, cast iron, brass fittings, while newer generations gleam with carbon fiber, titanium, and smart materials. Floating between each step: a translucent ghost overlay showing the KEY INNOVATION that enabled the leap (mathematical equation, material breakthrough, or patent diagram). Dramatic gallery lighting with each generation casting long shadows onto the generation below it. Include minimal floating data cards: year, efficiency gain %, weight reduction, breakthrough inventor. Background: gradient from vintage blueprint blue (bottom-left) to sterile white (top-right).
