Create a single-subject blueprint poster using only the main subject from the uploaded image. Render it as a clean white technical line drawing on a deep cobalt-blue blueprint background with a subtle grid. Use flat 2D schematic linework, orthographic contours, construction lines, measurement ticks, arrows, and minimal technical labels. The composition may also include 2-3 smaller inset studies or alternate views. Keep the layout simple and balanced with no shading, no 3D, no lighting, no extra objects.
