+This example demonstrates how to design a toy truck using BuildPart and 
+BuildSketch in Builder mode. The model includes a detailed body, cab, grill, 
+and bumper, showcasing techniques like sketch reuse, symmetry, tapered 
+extrusions, selective filleting, and the use of joints for part assembly. 
+Ideal for learning complex part construction and hierarchical modeling in 
+build123d.
