### Full prompt
```text
Finalize this rough sketch from the reference image into clean, precise CAD-style technical line art. Follow instructions and corrections from the blue text annotations, eliminating all hand-drawn roughness and ambiguity. Vary the line weights dynamically, applying thicker strokes for primary silhouette and ridge lines, and thinner lines for secondary details. Completely remove all blue text, annotations, and guide lines from the final output, producing only pure, crisp monochrome line art.
